no, weird thing is single player maps stil worked,
what i did recently was play the game, i installed mods and played those after which i completly deleted the game and the mods and installed the game again after wich only single player maps are showing up.
When you unistalled the game did you delete the CoH Folder completley? If you didnt there might have been something left. Steam (if youre using a steam version) Only uninstall the game files. no mods.
i managed to fix it, and to replie on silent ghost yes i did, what did the trick was tweaking my video options when i had set them on the lowest possible configuration i had problems so i increased a couple off things to higher settings and now its solved. its stil a riddle to me why i didn't had this problem before i uninstalled-reinstalled but anyway i can play again
