I'll be glad to help.
If you receive the "Trial Version Expired" message then you have the AudioLabel Trial Version installed. Please download and install the FULL version of AudioLabel. The link to the full version of AudioLabel can be emailed to you here:https://www.audiolabel.com/full-version.html
The file that is downloaded is named audiolabel_600_full_setup.exe
Once you run the setup file, the very first install screen should have the words Full Version
(as show below):
Please let me know if you need further assistance.
