patcher_cf doesn't load

I recently bougth a new laptop with windows 8.1 and when I wanna play crossfire the following happens:
1. I start CF_G4box.exe as admin
that opens the regular starting screen.
2. I click on the green start button
USUALLY that opens the patcher_cf.exe but it doesn't for me.

Basicly after clicking the start button it closes and does nothing.

I am using AVG on both of my laptops, but it only occurs on my new laptop with windows 8.1
I have tried re-installing the whole game but did not solve this problem
And also tried running CF_G4box.exe in compatibility mode for windows 7, vista and XP

I have tried playing it on my old laptop with windows 7 and this problem does not occur
