cant access forums

hi guys.....just wondering if anyone has resolved a similar problem.
After never having trouble accessing the forums or my account from here, i tried to log in yesterday to be given the message, you need to log in.
i entered my details, hit enter, and the page refreshed to the same place ie, enter your log in details. I entered again...same result. I shut the comp down, started, error message same result. I changed my password, that was ok....it sent the request to my email address.
i came in, tried the old one, error message "incorrect password"....good, i thought, it recognises my info. entered the new one, page refreshed to the same place.
AAAghh...
I emptied temporary web pages, and deleted history. Nothing.
I checked all my other favourites. No problems there. I put a request in to support. They sent a message saying to call. I did, and was told it was a security setting and no cookie was getting through. If all else failed, I should install Mozilla.
Now thats fine as far as it goes, but I had no probs until yesterday and have no problems with any other site.
I checked my Mcafee settings, and even tho id never needed to before, I put trusted site secondlife into both cookies and privacy rules.
Tried again, no access.
I even disabled my security and tried, no access.
I have no problem getting into game, but not being able to get into the forums, or my account page, without as now, going to my wife's computer is a pain.
Does anyone have any suggestions, as to be honest it didnseem to be a major concern when i spoke to tech support.
Thanks in advance.

(comp is a Dell XPS intel 3.2 dual processor with 7800 GTX)
