I'm not going to re-install, I have to many mods maps and objects. I've restarted my computer 3 times. I can try changing the rendering system, but I don't think that would be the issue. If that doesn't work, I'll try running as an administrator.
EDIT
I went to change the rendering mode in the start up box, but when I click the drop down, it only give me one option instead of the two. When I close the start up box and try opening it again, it will only give me the option of the other one. I think this is the problem, but I'm not sure how to fix it.
