Correct, I have no mods.
That was the first thing I did, check the game file. It did find two files that it needed to download, I did that, and this particular crash happened after that download. The interesting thing happening now is I verified the integrity of the game file just now, and it found one file that needed to be acquired. I downloaded that file, then checked again to make sure it was good to go, it was. I launched the game, and the same crash happened. So, I checked the integrity of the game file again--one file missing, downloaded it and checked twice, ran the game, same crash. So, I checked the game file again, guess how many files were missing according to the file checker: one again. So, that's the current loop I'm in. File is screwed up, fix the file, crash, file is screwed up.
One thing i did before getting on the forums was uninstall the game via steam, and reinstall the game, I had the same crash before and after. Any additional troubleshooting you all could recommend would be appreciated.
