CANNOT GET TO SUBMISSION PAGE

So, yeah, I'm going around minding my own business, so I decide to click on the "My Submissions" link, just to review stuff. Problem: it leads me to the main page with an error: "This page requires you to be logged in." I hit any other link, and it shows me logged in. I hit that, and it shows me not logged in. The cookie is obviously still in place, 'cause if I hit a link from that page, I'm logged in.

Fix? Explain? Do a jig?

EDIT: Wow. It's worse than I thought. I'm logged in on the forums, but NOT any of the other pages. That's majorly weird. Oh, and I'm on IE6.

Yes, it has. I'm not sure if it was a fluke or if it was fixed.

And I'm on a school laptop currently. Seamonkey kinda drains the battery a little faster than IE6 does (plus I can't really update anything).
