Every time i press start game in borderlands GoTY i get this error

Any ideas on how to fix this ?

I have the exact same problem on the GOTY Enhanced version, if anyone knows how to deal with it…

Your best bet would be to file a support ticket. It looks like the game either can’t find a file for the initial game sequence, or the file is corrupted. I would do the usual Steam ‘verify files’ thing. Also, if you had modified the config file manually you might want to revert any changes you had made.
