Error submitting online registration

Hey my CD key says invalid after I purchased it from Steam.

I have confirmed that my Firewall is set to allow all for gsb.exe is there more that I need to do?

How do I resolve this?

My Problem is my AVG firewall. I disabled it and was able to register and after I turned it back on I can’t connect again. Will open new thread if needed

You have to add GSB to your firewall’s whitelist, else the FW will prevent it from connecting, this is normal behavior for a firewall.
