Parallels - multi-user, same VM?

Just installed Parallels this weekend with Win XP Home SP2. Works great, actually very simple to get running and working. Very little effort. However, I installed it into my home directory by mistake, and I want both the users of my laptop (Macbook) to have access to it. I copied the /Library/Parallels directory to the Users/Shared directory (copy, not move, I still have the original directory in my Library). I launched Parallels from my account and pointed it to that directory as the default for Virtual Machines.

However, when I launch Parallels from the other account, it wants me to install a new Virtual Machine. I can't go to preferences to see if I can force it to point to the VM I already created.

Any thoughts. So far, Parallels has only returned a .pdf that says to do exactly what I did, without much else in the way of help.

Hopefully I'm missing something simple.
