BF2 Bootin me between map changes :(

BF2 keeps bootin me out between map changes sayin "this server does not allow modified content", i don't think i have any modded content apart from when i removed the annoying videos at the begininng which i have put back now anyways...
don't have this problem on any other servers.
any ideas?

Had a similar problem after the 1.03 patch, some servers would boot me and others were ok, and it only seemed to happen on certain maps. The checksumming thing does seem more stringent on some servers than others (might be a Multiplay thing as they tend to be cutting edge with their BF2 server-side mods)

Uninstalled and reinstalled and re-patched, didnt help.

Uninstalled again, deleted all the mods I'd installed (even tho they were in their own folders), reinstalled, repatched, everythings now 100%

So even if you havent installed any mods, I'd suggest uninstalling and then deleting whatevers left in the BF2 folder (in fact delete the folder itself) then a reinstall.

strange, i havent made any changes and it's ok now
