I had similiar problem with animation files. But in my case I installed female animation pack which caused some errors. And also I forgot to backup vanilla files and wasn't able to restore vanilla animation. -Game cache verifing isn't an option, It will cause much more errors with files I changed manualy during different mod installations. -Game reinstall isn't an option either. (I have about 100 mods manualy intalled to avoid crashes and make them max. compatible) So I was looking for vanilla animation files as the guy above. I'm very surprised he is got banned just because moderator "supposed" he's got a pirate copy with no evidence of that. So tell me what to do if someone dont have an internet connection at the moment, but want to be able to play the game he paid for. I mean the situation when u bought, downloaded and installed game using steam to a laptop and going somewhere, where is no connection to the internet. Sometimes it's handy to get rid of steam. But anyways...insanityman's advise to delete animation files and let the game restore them worked perfectly. Thanks man!
