I have every campaign except the Soviet ones. I found all the steam keys on Slitherine my page. I cannot find where to load the keys on steam.

16 Oct, I went in and found all campaigns locked. Tried validating. No luck. Reloaded Steam and Order of battle. What do I do now. If the answer is load keys into the 'client', could you be more specific for a luddite to understand.

I validated the files and now everything works. Thank you, Bye

I have the stream keys. I can't find where to load them. Do I go to Stream page or do I open the game in stream?

I recently purchased the Allies Defiant, Resurgent, Victorious bundle. I loaded the base game V9.2.3. I lost my exe file on my local computer. I loaded V9.2.3 on Steam. Steam does not recognize the campaign keys on my local computer. I tried to load the keys but could not figure out how to load them...
