Solved
Mass Effect 3 (2012) online pass error
I'll just say that I did everything as written here.
Nothing helped, always the same error. Maybe I'm missing something, please help me.
Thanks to EA_Shepard , everything works.
I'll try to explain how I did it for people with a similar problem.
1. As mentioned - deleted the folder with DLC.
2. The game doesn't start - throws errors
3. Clicked Repair game, and in the same window removed three story DLCs and the Genesis comic from here.
4. Miracle.... The game still throws errors for DLC, but multiplayer (and this is the most important thing for me) worked
