Game created from behind NAT

[pp79]

I have the same problem. There is a yellow shield next to almost every game. Unfortunately the link leads to nowhere (page not found). When I try to join a game it shows resource desynchronisation message. I'm up to date with patches but I cannot join a single game.
I used several solutions such as installing the game again but with no success.
Please help!

PS:Would the hotfix help? I couldn't find it so I didn't download it.
PPS:Found the hotfix and it didn't help. It appears that the pak archives are missing. Reinstall did not help.
