You Must Enter a Serial Number to Activate

Problem:

After installing Libronix DLS version 3.0, you are prompted to enter a Serial Number for a product that was unlocked and did not come with one of our 20-character serial numbers.

Solution:

Press the [Shift] key as you left click once on the words "Serial Number" in the Account Management window and a small Delete button will appear below. Click this button to remove the serial number prompt.  You can also hold down the [Ctrl] key instead of [Shift].
