When starting the WorkStation/user Interface for WinPak, I was receiving a Windows Error Message and if I hit OK for the Error message the program would close. This is do to the Anti-virus Program that the company was running.
By stopping the Service - Windows Audio and changing its start-up type to Manual should fix the problem.
This will also disable all Audio
