Log files and the logging levels can be found via the ReadMe.txt file located here:
C:\Program Files (x86)\Wavelink\StudioCOM\LogFiles
Open Services.msc, locate and right click on WavelinkServer and select Properties
Click Stop to stop the service.
Add -D (logging level) to the Start parameters and click Start. For this example I am setting the level to it's highest at 4.
Your log files will now populate according to the level set at the above location.
Be sure to turn logging off when you are completed with your troubleshooting to prevent excessive file creation by going through the same process and deleting the line from Start parameters
