Maybe deleting the .config File or checking in there? Perhaps try a different option in it, like making the map sepia. Otherwise I would suggesest running the game as Admindistrator, or perhaps installing a different Java Version, different Forge Version or a different Graphic Driver.

Giving us more Information would be good too. Like if it worked before, what for settings ingame and what for hardware you use, OS, laptop, etc.
