Thanks, MaG. Unfortunately, the saves aren't there for me. I did a search, since I didn't even see AppData as an option. I did find LocalLow, but there was nothing in the saved game folder there, and there was no Phoenix Online Studio folder. Maybe the Gamersgate version puts them somewhere else.
Or maybe the DRM saves are purposely hidden so they can't be transferred?
Really, it's only a save from episode 3 that I need anyway. I ran into a glitch at one point where Cordelia would repeat herself on a loop, and I couldn't progress. Finally, it just broke after I loaded the saved game, and I kept a saved game after that point in case I encountered the loop again.
I suppose I could just keep 2 copies of Episode 3 - the Gamersgate version and the GOG version - play up to that point to make sure I can get past it, and delete the Gamersgate version if all goes well. Do you think it would be all right to have both versions installed without them interfering with one another?
