I just wanted to post it but was waaay too long.
You guys are awesome, such a fast help!

Dear all knowing FAF-Guys!
I have seriously no clue what I have done wrong to get this startup of the client?
Does it have to do something with the current server issues?
I already redownloaded the game and got the installation fixed, did a restart, but that both did not help, so I guess a clean uninstall and reinstall won't help either.
But I will try this now, meanwhile if anybody got an idea I would be happy to get it back to running order again!

All the best
Phili

Thanks a lot guys!

Should have looked here before closer, but I am just not enough into coding or have not read it through well enough, so that I got it where the mistake was coming from...

Evening!
Sadly I cannot start up my FAF games anymore, whenever I try to host or join a match, after the loading screen comes it crashes in 10 - 20 seconds and leaves the following error log:

(I already tried to reinstall it, bought it in steam and connected it there to those steam related game files, before I used an old FAF installation from one of the first game DVDs when it came out over a century ago, then I reinstalled FAF, but nothing seems to help. The Issue is not account related, as on my desktop PC it works fine, just on my laptop it does not work...)

I would be sooo happy if somebody could help me, or tell me which files to reinstall, delete or replace, what to do delete during a fresh installation etc. Must be some crappy leftover files or something weird. Just don't want to reinstall all of windows...

Thanks for the help and have a nice weekend!
