Sounds like a potential issue with the game detection. Please navigate to the directory that contains the main game .exe and check whether it’s called “sw.exe”. That is what vorpX expects. Might show just as “sw” in your explorer if you have file extensions hidden.
Some games use different .exe names for different editions (e.g. a GOTY edition or similar), which might cause a detection issue.
If the .exe is named differently, try to rename it to sw.exe and also let me know the other .exe name, so I can adjust the profile for the next vorpX version.
Just researched the matter: there seems to have been a DX11/64bit update for the game some time ago, which probably is the cause of your issue. If still possible, please use the original DX9 version. I’ll check whether the new one can be supported.
