Okay. So I downloaded the game from GOG and found a topic on reddit that had some mods for it (widescreen mod, widescreen interface, and a quinn fix pack). I installed the widescreen mod and the interface and didn't get around to installing the fix-pack until after I started a game. The game seemed buggy, whatever. It crashed once in a while when I would go into a small area, but nothing that effected me getting through the game. Until I get to the Clerk's district and it crashes everytime I go into the Curiosity Shoppe (which apparently I need to go into in order to beat the game). I go online and search for some solutions for this. Apparently I needed to install the fixpack before I started a game, not after. Someone on a different forum had a similiar problem and he said he fixed it be keeping his saves, and uninstalling the rest of Planescape, then reinstalling it with the fixpack and loading his saves. I tried it and I put my old save into the save folder and now it crashes everytime I open my old save. So I basically lost the 20 hours I put into the game, and am super frustrated! I just wanna finish the game without having to start over, and even If I do start over I'm afraid the problem will arise again.

Does anyone know a solution? Is there any way to get my old save working again?
