I'm using the GOG.com version of GOOH and when I try to run it with v21 of your mod, I get this error message:
Failed to attach to game!
Your version of Saints Row: Gat out of Hell is not supported.
Check for an updated version of RadioEnabler!
The Saints Row Gat Out of Hell.exe has a version number of 1.0.0.0 in its details, and its MD5 hash is 99be16b61980cd02e3149032d368aaa0. There's an injected.log file, but it's empty. The RadioEnabler.log contains only one line:
[RadioEnabler] Opened log file.
Am I doing anything wrong? I don't claim to truly understand what's going on, but I guess your mod requires certain offsets in the EXE to be exactly where they are. And these offsets seem to differ from the Steam version.
