Game Doesn't Start

Hello there,
My game was working just fine but in the past 2 days, I wasn't able to start the game. The launcher stars but then when I press 'Start' the game doesn't launch.
I tried:
-reinstalling the whole game
-deactivate my antivirus
-Uninstall antivirus
-Update windows
-Put the game in another HDD
-Drag the launcher inside the client's folder
-replacing the .exe file with the newest available .exe launcher file

Do you have any suggestions?

PS: I am referring to GamezBDO
