Downloadable Contents, Connection Issue

It is 6 months since I played DS3 with no problems, I was able to access the "downloadable content" with no problems. Now I found that Dead Space 3 Awakened is out. I installed the game again, started and clicked "downloadable content" but it said "in game origin is not available" WTF...

After some research I found a solution to the problem, run the game in windowed-fullscreen mode. I was so happy but not for long... well guess what, the problem with "Cannot retrieve information from Origin. Please check connection and try again." appeared instead and by the look of it the problem is here pretty long time looking at the date of the 1st post (05-02-2013).

I have tried everything in this topic to fix it but it still does not work. My PC is still same like 6 moths ago when everything was working, my ISP is also still the same (Telefónica O2 Czech Republic) and a friend of mine who is working for them told me that the problem is not on their side, they are not blocking me so where is the problem... ?

Well I know where it is in EA and it looks like they don't give a **bleep** about it since they did not fixed any of the 2 problems above.

I have 8 games in my origin account and this is the second time since I am not able to play a game. On the other hand I have collected 148 games in my steam library during 6 years and only once I was not able to play a game, it was just not working on my PC...  so they gave me my money back.

See EA, you should learn from pros and fix your **bleep** together already because this is getting anoying.
