It was not doing this the other day. I go to play SH single player and when i go to the main menu everything is white and grey. So i uninstall and reinstall and everything is still grey and white. You know how on some maps with missing textures theres a white and grey border around them. Well this is what i have even on the options menu for sound and everything. Maybe i should just go buy another copy of SH now.
I had this problem with a mod I tried using. They all turn out white & grey boxes. Clean out any custom mods you have, if it still happens, reinstall with my guide:
