I made a new account in 4d1 and when joining server after 3 sec i get kicked out with a message"Steam Authorization Failed"??? any help will be appreciated.....thanks
Try running as administrator should work then
1.) Either you're not running the latest version or you have internet problems (Restart the game a few times)
2.) If it keeps happening, then you're HWID banned and will not be able to play IW4M/IW5M anymore.
Since there are no current bypasses for this ban and since asking/begging for hacks is not allowed (Because we all know that's your next question, "Make me a ban bypasser?" etc.) AND since there's no other solution for this as we're not 4D1:
