The only map i cannot seem to play is Highway Tampa as i get the "please use unmodified content error" i can play any other map on all pubby and GC servers but not that one, installed and reinstalled several times from different filecloud, gamerhell and so on.
So what the Feck causes it and fix? So without install and reinstall BF2?
Last time I ran into that I think I had some files on read only somehow and couldnt overwrite with the update. The update never said a word. Or missing the archive.md5 file in the folder.
You may want to manually delete that level folder and re-install the map.
