When i updated my game to U18 i could not Connect to All exept 3 servers online. Also When i installed the patch, it Locked the game and i have used my 3 unlocks already
<sorry if this has been posted already>

U18 is no longer compatible I believe. You need U19, U20 or one of the offical patches. As a test patch user you are expected to keep up to date by reading Scawens posts in the test patch forum. If you don't then it's better to ignore test patches.

thanks for that. I got the U20 Patch and i can connect to most Demo servers.

you can always email the devs for another unlock code. If you are nice about it and have a legitimate reason, they will give you another unlock.
