This problem has been going on for months and I never found a solution. I've let it sit for hours and nothing happens, it keeps on saying Authenticating: Validating Key forever. I hate to spam the help section with so many of these topics. I've searched everywhere for a fix but nothing so far has worked. Does anyone know how to solve this problem?
Notes:
Port Fowarding does nothing for me
Using steam version
No Proxy/VPN
