I deleted the cache files and downloaded the new awesomemod, but I"ll try again to see if anything changes.
Edit: I deleted my cache files and it did nothing. I know it's not a specific mod because the game won't load even if I have no mods installed. The only thing in the mod folder is the enablescrpterror, which is what I think is keeping it from working.
Did you also delete the package folders in the WorldCaches folder? I notice most neglect to mention these specifically.. I mean while deleting the Compositor, Script, and CASParts cache files all do resolve specific problems (the script cache being notorious for startup crashes), deleting the World Cache sounds like it "might" help more in this instance. (Since I notice you mentioned in your first post that you crashed when loading a save\neighborhood. Though I might have misunderstood.)
If you've already done this though, or are just crashing at the main load screen now (in which case removing the World Caches won't help at all), I'm not sure what the problem might be. I actually believe I ran into something similar sometime back though, long before this patch, but it seemed to resolve itself after multiple attempts.. which is odd, but this game seems to be full of weird voodoo.
