Protocol 25

[killerblade]

I've just bought the game and can't join a multi player server, keep getting the message 'This server uses Protocol 25' can't find anything on the forum about it???

Try downloading the v1.01 patch from JKFiles. It should be in the top downloads list.

If that's not it, then the server is probably using JA+ mod, so you'll need the clientside plugin for it. You can get the clientside plugin here.
