Got the same problem with a friend of mine (he's not confident with his English to post here). It looks like he and another guy who plays on the same server just have the same CD key hash (others servers are fine). Any DEV can take a glimpse at this problem? I know the hash is hardware locked, and any proper method of changing it must be confidential, because of evading bans and so forth, but is there any fix to it?
So yeah, tried uninstalling the game, cleaning Documents, the registry, etc as much as I could find, reinstalled. Still the same issue 'CD Key is not valid'.
I ran into this issue earlier; as in if you try to join a "Deployment" server, you receive a notification stating that "Your CD-Key is not valid" or something like that to some extent.
I had attempted everything mentioned in this thread and still had the same results.
BUT after reinstalling, trying to join a "Deployment" server once more and again getting the same message, I tried something else. I then joined a "CO-OP" server, loaded in, left and attempted to join a "Deployment" server. It worked. Hope this helps someone out.
Does anyone know how to fix this!? I want to play PR again after years... and I can't because of this error! Please help! I'm getting this error at HOG Mixed Maps server...
"So you want to live forever huh? And why in the name of the Allmighty are you here!?"
