I dl'ed the mappack and installed it(correctly i'm not sure, i havent had to dl any of the standard maps since then so i assume its in there correctly)...

But yet when i try to connect to most(so far all that i know of) servers running SF_Testmap i gives me the error that i've got a different version then what the servers running... is this a server issue or is it the map on the mappack ?

I believe that means the server version of the map is not as up to date as yours.

I used to have the same prob when i had a Dedicated CS server running, i was kicking myself for days wondering what its all about then i realised....if you dont keep updating the server and a new updated version of the map is released that happens...

In otherwords, just join another server.
