Missing Perks/Skins/Achievements, unable to connect to server
I got a new rig nearly two months ago. Since then, everytime (with a few exceptions) I launch Killing Floor, I cannot access my perks, skins and achievements, and when I try to connect to a server I get this message:
1/ "Delete all files under \\steam except Steam.exe and the steamapps folder, then reboot"
I was able to play after the reboot, and after a few hours without shuting down the computer the problem came back.
2/ "Close Steam, delete the steamapps folder, start Steam and reinstall the game"
3/ "Uninstall Steam, and install a new version from http://www.steampowered.com at the root of your hard drive"
Still no change.
4/ "Try the answers in this thread: http://forums.tripwireinteractive.co...ad.php?t=51908"
Totally irrelevant, and (of course) nothing works for me.
5/ "Please give me a screenshot of the problem"
6/ "Could you give me the msinfo report?"
Here it is! File
7/ "Make sure your network is properly set up for Steam. Also, disable the softwares listed in this message"
Doens't work, even when I totally remove the softwares listed.
Did it a dozen of times in 6 days, didn't work.
9/ "Have you tried to ask for help on the Tripwire forums?"
Well it's a Steam error, but here I am.
So I need help. Killing Floor is currently the only FPS I play, and I'm not playing it for nearly two months
I must add that sometimes, the game allows me to play for a few hours. Then I quit KF, do something else, and it's gone again.
