Whats going on? Why I can't I do multiplayer mode?

I use to be able to join other servers, but now I can't. I checked my firewall, but its allows and accepts srb2. Usually when I try to joining it says " You need server _____". Yes it had no name and the server name was blank and it would also say "You need to have server SRB2' When I already have it. Its been about two monts since I haven't played this, so can anybody help me? Thanks.

Do you have the current version of Srb2?

The one that is august 2006? I tried to download it, but it looks like it was downloading without telling you the percent or showing a white bar getting filled up with green rectangles. I'll try again.

You need to have 1.09.4.

When you download it try again.
