Errors Loading

Ive contacted EA support, I've changed graphics and my cpu data and everything i can. even reinstalled fully. I can't load a save if I exit the game and reenter. my characters are completely inaccessible unless I let the game fully hijack my pc and keep it open and on all for all hours of the day- which isn't possible. i get the notification after like 3 mins of loading that there is an error loading or processing this request or something like that. please help.
