I downloaded the game an patched but while patching it said some error or whatever "retry" or "cancel" well i tried it wouldnt work so i closed the patcher waiting a few mins opened it..it started to patch....then i got the same error did the same thing....it finally patched but now when i try to login it says "disconnected from the server"

Try reinstalling the client.
Try re-downloading the file.
Turn off your firewall.
