Check the WOFF FAQ PDF (it's in the documents folder in the WOFF directory). Be sure you open and run Windows Media Player Legacy (just type Windows Media Player in the search bar in Windows 10 or 11 and it should suggest it). To make doubly sure, you'll need to open the Command Prompt with admin privileges and add a particular dll to the Windows registry. You can find the command in the WOFF FAQ PDF. I'm away from the gaming rig so I cannot recall the command off the top of my head. Hope this helps!
