I didn't make it!
I've been playing foc with z3r0x's addon 3.5 for a while now, but for some reason, when I was trying to tweak a couple of the xml's to my liking, I tried to start the game, and only the unmodded version played. I tried re-installing the base games, and re-downloaded the mod and the mod launcher, but nothing seems to work. I even tried several other mods with no luck.
So what happened, and does anyone have any ideas of how to fix this?
