Semi-educated guess, but if you can join other servers without a problem it is more than likely that the servers where you can't join are pure ArmA2 and aren't set up for OA and the BAF and PMC. I may be talking c**p mind
Bump. I have exactly the same problem. I have Arma 2 through steam and Arrowhead normally, so I play through Combined Ops. I bought BAF the other day and now the server I use all the time will not let me on, even though they use the BAF in the server. My friends all have the BAF pack and can play fine on it.
The only reason I bought the pack was to play online; it would be a total waste of £8 if I can't get this problem fixed.
The problem is that in my steam folder I only have an Arma 2 folder, not an Operation Arrowhead folder (because I don't have it through steam) and when I've been installing to the Arma 2 directory it hasn't been working.

I have purchased the BAF Addon via Gamersgate. I just checked the details there and noticed that these stupid morons have not yet updated the BAF Addon on their server, so it is still 1.02, while it has already been updated up to 1.03. This is causing my issues. What can I do exept rebuying that one via my Sprocket account?
Before someone asks...I know that the OA 1.60 patch actually comes with BAF 1.03 patch, same for PMC which is lifting that one up to 1.02...I installed these ones and it nontheless keeps them on 1.02...try to reinstall the patch
