alyssastanton12 Have you installed NRaas ErrorTrap or another core mod? What you've described happens sometimes when a core mod is present that's not build for this exact version of the game. There are very few core mods out there, seven common ones last I heard, but if you're not sure, you could simply remove your entire Mods folder as a test.
If that's not the issue, please provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
