taking screenshots on this map crashes my game every single time, any reason/fix for this????? its seriously annoying

 

I REALLY WANNA PLAY SO BAD </3 but like when i launch the mod, my game crashes with either, world at war has stopped responding or something about vram. i have 4gb of vram so i dont see how this would be the cause. i play all the time all types of maps on highest settings and have no problems
