I have the same problem bud. I can log in and then after a search or I navigate to what I'm looking to download I get logged out somewhere in the mix. When I log back in it puts me at the downloads home page again. Endless loop.
From what I understand Senaxx is making a new site layout so hopefully it's fixed soon. In the meantime you can try a different browser. I get the problem on Firefox Nightly. You might try IE or Chrome
Fiery the angels fell. Deep thunder rolled around their shoulders... burning with the fires of Orc.
