CK2 has stopped launching on Steam

[MarshalGivens]

CK2 has stopped launching on Steam since last week. Anybody got any idea why, or how to fix it?

I'm not on the latest patch, but I was able to launch and play CK2 on Steam just this morning. You may want to contact Steam tech support if you're still having issues.

Will do. Thanks.

So it starts without Steam ?
Either way i'd contact Paradox tech support.
I'd recommend to post in the tech support subforum, unless if you want the conversation to be hidden.
