Mass Effect 3 (PC) crashed in Online Mode

No, the servers are still running. You mention " checking downloaded dlc part." Can I check if you've tried running a repair? To get this option right-click the game panel in Origin. 

If this has been tried already or has no luck, can you try restarting with a Clean Boot and see if this affects the game's behaviour?

Thanks. 

thank you for reply. I did as u said but it did not work for me. I reinstalled the game, still same problem persist. I did some googling and find out the solution.

solution

1. I go offline in origin

2. start the game

3. Alt+tab (Shift+F2 is not working for me ) and select go online 

4. Return to game - select connect to EA Server

5. Profit,, game is working, played hours of multiplayer

Problem : My Origin in Game is not working. I can't invite my friend to the game, any workaround ?
