Cannot Access the Game on Steam

[HerrRitter]

I'm a big fan of SH5 and the Grey Wolves Mod. Everything has been going well for several days.



Yesterday, I tried to play the game, and after the screen went blank (subsequent to the GWoS screen), I expected to see the "Synchronising saves" screen, any second. It never happened. I can't get into the game, at all.


I checked with UPlay to make sure that they had my product key, and they did.


UPDATE: I verified my local files (which I knew would wipe out the mod, and tried playing the vanilla game. It worked perfectly. Accordingly, I re-installed the GWoS ... and I know how to do it, by the way. Suddenly, I am getting the STEAM application error 3:0000065432 error. There are a lot of cures for this, on the internet, but they are mostly for Skyrim, and I didn't find one for SH5. I want to throw someone off my bridge ...



Does anyone have an idea why this is happening?
