utlMemory.h error

Im trying to start my Dedicated server and when the server starts loading the files, near the end i get some error saying:
ultmemory.h (322) : Asertion Failed: IsIdxValid(i)

I dont know what this means and I’ve never had this problem before. I also had my Dedicated server running successfully two days ago. Whats wrong?

Ba-Bump! its been 36 hours and no reply :’( lol I dont think anyone knows whats wrong.
