I assume by 'My Content' you mean 'My Games'? That's the only sidebar menu that comes up with icons, and Mass Effect 2 has never been visible in that menu, simply because it has very little (visible) integration with BSN beyond a repository for one's DLC.
Have you tried logging out of the site, and logging back in again? It might be worth logging out, clearing your browser's cache (And, if you feel like it, cookies and most other options) and then logging back in. Also, does it work with a different browser? If you're using Internet Explorer, I urge you to switch to something like Firefox, Chrome or Opera (Due to IE being rather insecure) and trying the site on that.
