3am LineScope - License Agreement

IMPORTANT - READ CAREFULLY: This End-User License Agreement ("EULA") is a legal agreement between you (either an individual or a single entity) and 3am Systems Ltd, a private limited liability company registered in Malta. By installing, copying, or otherwise using 3am LineScope ("the software"), you agree to be bound by the terms of this EULA. If you do not agree to the terms of this EULA, do not install or use the software.


2. GRANT OF LICENSE. On purchasing a license for the software, you are authorised to use the software on a number of computers corresponding to the number of licenses purchased. The primary user of the computer on which each licensed copy of the software is installed may make a second copy for his or her exclusive use on a portable computer. Under no other circumstances may the software be operated at the same time on more than the number of computers for which you have paid a separate license fee.

3. RESTRICTIONS. You may not rent, lease, or lend the software. You may not reverse engineer, de-compile, or disassemble the software, except and only to the extent that such activity is expressly permitted by applicable law notwithstanding this limitation. You may not publish or distribute any serial numbers, access codes, unlock-codes, passwords, or other end-user-specific registration information that would allow a third party to activate the software without a valid license. You may not use this software for unlawful purposes.

4. TERMINATION. Without prejudice to any other rights, we may terminate this EULA if you fail to comply with its terms and conditions. In such event, you must destroy all copies of the software.

5. COPYRIGHT. The software is protected by European copyright law and international treaty provisions. You acknowledge that no title to the intellectual property in the software is transferred to you. You further acknowledge that title and full ownership rights to the software will remain the exclusive property of 3am Systems Ltd and you will not acquire any rights to the software except as expressly set forth in this license.

How do I activate my copy? To activate your copy, run the program, select Help->About->Activate, and email us your Machine-ID text (cut-and-paste) and CD-Key. We will reply by email with a license key that activates the product on your computer.
I formatted/upgraded my PC. How do I get a replacement key? In general, we will re-issue a replacement key at no cost, after basic verifications.

However, for repeated requests within a 6-month period that exceed the terms of use, we charge a key re-issue fee per incident.
How do I get additional keys? For regular users, you need to get individual software licenses, which can be purchased at a discount.

For temporary over-provision situations, you have the option of paying a key re-issue fee per incident. While cheaper in the short-term, such over-provisioned keys cannot be used as a basis for no-cost re-issue in the future.
Which operating systems are supported? Windows 10, 8, 7, Vista and XP (32/64 bit) are supported.
What are the specifications of the LineCoupler? Our LineCoupler captures high quality recordings of telephone calls and fax/modem exchanges on traditional fixed lines, PBX and telephony gateways. It delivers excellent gain flatness and low distortion, with minimal insertion loss.

I get "This setup requires the .NET Framework version 2.0" when trying to install the product on Windows 10/8. You need to enable the .NET Framework 3.5, which is an optional Windows feature:
  1. Press the Windows key on your keyboard, type "Windows Features", and press Enter. The "Turn Windows features on or off" dialog box appears.
  2. Select the ".NET Framework 3.5 (includes .NET 2.0 and 3.0)" check box, select OK, and reboot your computer if prompted.
I get "Unhandled file format" error. What can I do? To convert an MP3 or WAV file to LineScope-compatible format:
  1. Install Audacity, a free audio utility.
  2. Open the MP3/WAV file with Audacity.
  3. Change ‘Project rate’ to 9600 Hz (from status bar at the bottom, type 9600 and press ENTER).
  4. From menu, select Tracks->Mix->Stereo track to mono’, if needed.
  5. From menu, select File->Export->WAV. For Encoding, use Signed 16-bit PCM.
Then, open this new WAV file with LineScope.
I get an exception when trying to record. What can I do? This can happen when a default recording device is not available (for example, no audio driver installed, or device removed). You can check this from the Sound applet in the Control panel.
Some data appears encrypted. What can I do? This product does not have built-in decryption capabilities. In a testing environment you might want to turn off the encryption or else test with known keys.
