i can't get into a website for months now. it is just me.
i've deleted cookies.
i've tried to change my dns.
i can get in sometimes when i restart my computer, but as soon as i click something i lose access.
i'm on 10.6.6.
I would try a different browser. You can download and install a browser you don't normally use ie Chrome, Opera or Firefox and try the site in that browser.
