I'm seeing the same problem as well. It keeps re-occurring as well. Does it mean this update has been withdrawn or is there a problem on the parallels server end?
I get the same error, and found the download page, but after logging in no email ever arrives. I've tried a few times now, the first more than a week ago. (My email address is correct and there's nothing from Parallels in my spam folder.)
I wish Parallels would wise up and post the direct download link themselves. (And/Or fix the in-app update mechanism.) This has been the most frustrating experience I've had with a software company in some time. It's definitely enough to make me give VMWare another look next time Parallels releases a paid-upgrade.
