Mass Effect 3 Multiplayer "Not Responding" every 2-3 minuttes.

Okay, now i looked through forums, cant find a answer anywhere, maybe i looked the wrong places, but here i go.

I Downloaded the Digital Copy of Mass Effect 3, for only intension to play Multiplayer (Completed Story on PS3).

More or less ALL the time, no where if i am in the Menu or ingame multiplayer, i receive a "Not Responding" on my game, this happens every 2-3 minuttes, and the screen freeze for 10-15 seconds. CPU drops to zero. Sound is still on, i have immensive good FPS, over 60+ game runs super smooth, but i cant play the game, because of the "Not Responding issue" it kinda ruins the game.

I hope some people out there knows of this issue? or can redirect to a solution of this.

Thanks.
