I'm starting to get fed up with steam. I just bought Anno 2070 and I'm getting failed to contact the key server. Supposedly this has been going on since the sale went live without any resolution. They have either run out of keys or the authentication server is down, however all my other games work so I assume it is a key problem. This is the third time this has happened in the last 6 months, and it has happened at least 5 times in total.
