X-Trap Error:02-0300-00000000-612

Sup everyone , I don't know if someone will can help me with this X-trap error.
I searched on the web for a solution but nothing helped me.

I get this error when i start the game. I cannot reach the window that ask me to login.
So i get this error that you can see here when i load the game.

I'll tell you what i tried ; - Closed all my firewalls ( so it's not the firewall )
- Opened ports on my modem ( it's not port forwading )
- I launched the game as administrator
- I redownloaded the client
- I deleted my NOD32 antivirus


The problem appeared before the last patch.
I redownloaded the game one time and it worked then i jumped on another game , Came back then the error started again. That's weird.

Anyone have an idea ? I have almost nothing on my computer.

I have windows 7 by the way.

Thx
