I strongly suggest logging into the Bohemia Interactive forum board. You are very likely to get help and advice straight form the developers.
I would be interested in trying that server - you could PM the details of the server... If you want.
If you have ARMA 2 boxed and unpatched, then I would strongly suggest you get the latest updates.
Out of the box, ARMA2 has a lot of bugs...
Another thing - check that you have the add-ons required by the server and load them with ARMA2. even if you have them, but are not loaded, the connection will not work. You load them by adding commands to the shortcut target. The forums describe how this is done - I cannot remember atm...
ARMA2 + addons is the best military sim out there. The support form the community and the developer is outstanding.
