"Login Accepted" for ages if I join, or crash... or empty game menu if I join... and game crashes when loading map if I'm host... (I can't add any logs, I dont even know how)
Try --no-mods and for logs see this sticky from top of support forum: https://forums.uberent.com/threads/how-to-find-the-pa-logs-and-game-lobby-ids.70299/
That looks ok. Can you try doing a clean boot? Sometimes other software interferes with PA in unexpected ways. Instructions are here: http://support.microsoft.com/kb/929135/
Can you post PA logs that mikeyh mentioned? Specifically a log from where you tried to connect to multiplayer and failed. The easiest way to do that is to delete all of the logs, start PA, join multiplayer, watch it fail, and close PA. Then there will be only one log.
Oh, I think I see what's going on. Do you by any chance have GOG Galaxy installed? It's been known to crash PA for some reason. (Though you seem to get further than most for some reason). Could you try uninstalling it?
GOG isn't instelled and I cant find any files of it. Another report: "Login Accepted" when I'm joining someone's game and before a moment crash.
Anything installed from this list: http://steamcommunity.com/app/233250/discussions/2/558751813508748383/
Could you verify the files? I think you are using the UberLauncher to play, right? Just press [VERIFY] a couple of time and try again. (If you do use Steam, you need to verify the integrity of the game cache.)
Meh, sorry this is being so annoying for you... Well, if you are still up for it, we can try a few more checks. One you could try is the SFC tool that comes with Windows. It checks your system files for corruption. Instructions are here: https://support.microsoft.com/en-us/kb/929833 Another potential problem could be the graphics drivers having some sort of problem. The easiest way to check that is to download the latest drivers again. Then uninstall everything graphics card related, reboot, and then reinstall the freshly downloaded drivers again.
"Windows Resource Protection did not find any integrity violations." I have installed drivers few days ago, but I can do it again if it's necessary, is it?
Well, the key is uninstalling the old ones completely first. If you did that when installing the new ones, then you should be good. Not sure what else if could be. The crash reports that were in your earlier logs seem low-level random crashes. Your later logs don't have crash reports at all, they just stop. Is PA the only game giving you trouble?
