My Sims 3 also went red.. Right after installing a few new mods/cc. I had a back up from an earlier saved game so I moved the mods out and put all the mods back in except one mod. Sims 3 blessings and Disasters. So my question is now, is it the mod or was it my other saved game that was corrupted? I will probably be testing it tonight by backing my game up and then reinstalling that one mod. The only reason I am blaming that mod is because one other person said it caused red screen. The other 200 that downloaded it had no problems. I guess my actual question is do you think I should download the mod again and try to reinstall or do you think its the mod that caused the game corruption. What causes game corruption? I really want to understand...
