Fatal Error problem

[MickeyD]

Played this game for an hour or so, and I quit to go do something else. I went back to load my save and every time I push continue, it says Fatal Error: Could Not Load World File "

I've been reading that this issue occurs with others specifying map files and whatnot, but mine does not even specify a file. I just says ". I tried verifying the cache, but it didn't change anything. Does anyone else have this issue, and possibly know of a fix?
