There were four of us who failed to get into the server as we were listed as 'null' rather than our steam ID. Despite his best effforts, Watchman couldn't manually boot us from the server as we were all logged in via our IP addresses.
Many thanks for trying and hope we didn't disrupt his session .
When HL was available as an alternative I could always get in - Steam Client is definitely a 'pain in the ass'.....
