Can't launch the game it says "Server returned bad data"

Everything works perfectly few hours ago then this happened. Every time i try to launch the game it kept saying "server returned bad data. There could be technical difficulties. Some important files are missing. Check your internet connection settings"

Nothing seems to work. I've tried force checking multiple times now but does not seem to work. I also did a clean install, but it's no good.

 

Have you checked if your firewall is blocking the files?
Do you have a third-party anti-virus like BitDefender?
Have you checked with your Internet Service Provider (ISP)?
Maybe they are blocking the connection in which case you will need to use a VPN.

If you are using Windows 7 (outdated now), then this might be helpful: http/forum.gameznetwork.com/threads/dear-gamezbd.231255/#post-2184786
