Then we may have failed to set your session cookie properly, sorry about that!
If your browser is configured to not accept cookies, then most unfortunately you won't be able to log in or download any results. Normally browsers accept cookies from the site you're visiting just fine, so this is somewhat rare - you may want to double-check your browser's settings.
If your browser is configured to accept cookies but it's still not working, then there may be a stale session cookie with the wrong settings lingering, blocking the correct cookie. Could you clear your cookies for this site and then give it another shot?
Thanks, and if the problem persists, please let us know!
