I keep getting this error every couple of days and always end up having to completely reinstall my game just so I can play it all. Its getting really annoying. I can't get to the launcher, I get the following errors:

File access failed during version check [11018][19900][2]
File access failed during version check [11018]

I don't have any anti spyware programs like malware bytes running or anything of that nature. I have no idea why the game works fine for a few days and then decides to give me the errors. I'm running it from steam as well.

Someone please help
