Cezar.Lica - I have looked into your concerns. As far as I can tell, you are able to update your profile. Please try again and let me know if it works properly. However, there is a bug with the newsletter subscription that I have referred to our Dev team.
I was able to see the bugs and feed back just fine. Please describe your issue in more detail.
I used IE8 to view your profile and it seemed to work. Try your different browsers and let me know if you see any difference.
Cheers,
Matt
