What member features you want to access and cant?
If you are getting pop up ads when you log in with your gold member account, then it's definitely about the malwares in your computer.
Try either Firefox 4 or the latest version of chrome http://www.mozilla.com/firefox/fx/, download Comodo internet security (free) http://comodo.com/ and Spybot (also free). http://www.safer-networking.org/
install & update them, run a through scan with them, clean your browser's cache and temporary files, and try logging in with your updated or upgraded web browsers.
I paid to become a Gold member but am Still getting pop-ups on my screen & I cannot access any of the benefits.
