Need Help ! HL2 beta MegaBuild not lunching game

[5qUe]

Hi
I have a problem with HL2 beta MegaBuild. The problems are starting when I try to lunch game from LeakNet Mod Launcher (newest version). When I hit the start button from the left side the game is not lunching I waited 5 minutes to be sure , in task menager the process exists but it does not consume more memory to finally start... I've tried to turn off antivirus and even install patch 4.1 but still nothing...

ps. Sorry if I made some mistakes while writing this post.. english is not my native language.

This sometimes happens to me too. Clicking "Stop" and starting it again works for me.

Also the oficial Mega Build thread was created for this kind of questions and problems, so next time fust post any of those in there instead of creating separate thread.
