In Progress Game activation problems.

[Jinno]

My friend has recently gifted me a Steam version of WFAS. I downloaded it, played for a little bit, and then the game requested a serial key. It was supplied by Steam, but regular and manual activation don't work. There lies my question - is there any solution to this problem?

If you are playing through the Steam, there should not be any activation dialogue. Steam should handle that on its own.
