FAQ
Q: I see a white screen and nothing after that
A: You most likely have an anti-virus such as Bitdefender, malware bytes or another antivirus potentially blocking the protocol in your web browser, consider turning it off temporarily,
whitelisting the website or using a device such as your phone to view the update process
Q: The game control panel shows it as the old version still so it has not updated?!
A: The game control panel queries your game server after a while once it's up to get its name, it will NOT show the active version, to see your server's version,
please view your server in steam servers to see what version it actually is
