I finally got in, I had to use FireFox though.
Am I really the only one having lots of issues with MS stuff lately?
/EDIT:
Nevermind, firefox wouldn't download the file, it just kept trying to dowload "DownloadDetails.aspx". not the actual SP1.
So I had to delete my IE cookies, which did work, but now I'll have to relogin to all my websites (home banking, forums, youtube, etc)
I know it's trivial, but really I just sort of expect these things to work.
