The OSGN

so when I erased my map gg_cargoship and download it from the osgn server its still telling me that my map differs from the servers and I have done this many many times and each time the map comes up it tells me this same thing ...any ideas...I dont like the map anyway but i would like to play and seems that everytime I do have an hour of free time this dumb map comes up

No idea. It is probably in a cache some place. Try google, because I sort of remember something about this.

make sure you delete the nav files and other files as well not just bsp, do a search for cargoship , and delete the remaining associated map files
