Windows Defender might say "Windows protected your PC...", this is because the Client's Installer has not been run by a lot of users. To continue, click More info, then Run anyway.
Now in the Odd chance that you do not have this option, you must do the following: 1 - Open up Windows Security Settings 2 - Click on App & browser control 3 - Under the "Check Apps and Files" section, select the Warn option. (if already selected, contact us) 4 - Run the Client Installer again After this, you should be able to play games properly now! :D
