Hi Jensen,
Did you also get 2 seperate license keys via steam when you purchased it? Other steam customers have reported this.
You might need to register that other key to your forum profile instead of the one you have there atm, or both, rather. This was a problem for others aswell.
As for the patch not changing the 2.2 to 3, I think that's a little hickup with Steam not yet having everything clicking. (registry update might follow)
As long as you can see the mission editor ingame, then you're good.
Regards,
Fred
