Buying DLC's for Mass Effect 2 not working!

I have the same problem with ME2 on Origin. 

- buying DLC's for Mass Effect 3 seems to work ok (after clicking Buy button a popup with loading circle comes up for quite a log time and then a site appears when I can select how much Bioware points I will buy - as currently I have 0 Bioware points),

-buying DLC's for Mass Effect 2 is not working (after clicking Buy button a loading circle comes up, but after a short time a blank page is displayed in that window and nothing else is happening).

Please help us! I don;t want to start playing ME3 before completing ME2 DLC's.

Thanks in advance for any help!

I've returned ME2 for a refund in Origin. Played ME2 retail version long time ago and this time bought the game only for DLCs which I'm not able to buy...

I've seen on the forum that this problem exist on Origin at least from December 20:

The workaround mentioned on that topic is not working for me, because I cannot register new received product key on Bioware site (newer keys seems to be not recognized, yes I've added proper '-' character to the key).

It's a shame for Origin, a platform aspiring to compete with Steam, to have unresolved issue for 16 days :/

The same happens to me when I try to register either my Mass Effect 2 key (obtained through Origin store) or even my Dragon Age Origins key (obtained when they were giving DA: O for free and such) on Bioware site. Oh well 😞
I think I'll try to buy a cheap DLC for ME2 on Bioware site to see if it works for me. I'll leave a comment here once I manage to do it 🙂
