Hello Mamoso.

As I told you in the Help Room/Private Message, try to follow this link :
https://support.voobly.com/display/vkb/KB1010+My+Voobly+or+game+keeps+crashing+when+attempting+to+launch

Also, try to reinstall first Voobly and change the game to Age2HD since I know you got both of them (by following the cleanning installation of Age2HD + compatibility patch)

Looking forward to hearing your feedback, amigo

Solved. For anyone who has the same problem, he has to uninstall his anti-virus (which is NOD32 in this case). He had to wait 5 mins to join/host a game or sometimes Voobly crashes.
