Mass Effect 3 Load Failed. Cannot connect to server

What is frustrating, that: yes, I could finish the game even without "galaxy at war" system and still get the needed ending; however, I finally decided to play it afer so many years and ordered all DLC and ad-ons - to get the full experience from it, not balancing on compromises.

So, I really hope, that support will come from EA and technical service will fix it in some way: It would be understanable to not to get support for the old product if, for example, some notification appeared, when you buy it, or the price is so low, that it idicates the same. But, no - no notifications and price, though much lower, but is still on some average level.

May be it is possible just to fix this figures thru some file? In order we have a possibility to manually change it in accordance to our inner feeling of our progress in multiplayer?
