Parallels 8 - Mavericks - Windows 8 Password Required

Upgraded(?) to Mavericks. Parallels wouldn't start.

Downloaded and installed the free update to Parallels 8.

Parallels and Windows 8 started, but a user name and password were required. Had no idea what they were. Searched the knowldegebase.

Followed the instructions at http://kb.parallels.com/en/114193

Got to step 5 and received the message: "Unable to open new session in this virtual machine. Make sure the latest version of Parallels Tools is installed in this virtual machine and it has finished booting."

I presumed that the newest version of Parallels included Tools, or is that a separate download and install?

Tried restarting virtual machine from the menu. Nothing happened.

How do I get past this user name/password issue for Windows 8?
