Painter Essentials 3 problem

Hi, I got Painter Essentials 3 w/ my new Bamboo Fun tablet.  The Painter
software seemed to install fine, but now when I try to open it it shows the
splash screen for a few seconds, white box on left of screen and shuts down,
if I click on the Painter "Register" icon I get a Windows error,
"user
registration app has encountered a problem....".  I'm running Win XP sp2,
I
have also tried to uninstall and re-install but I am getting the same
results, I have also updated the drivers for the Wacom Bamboo tablet -
nothing has helped, any ideas on what I can do???  Corel won't help me
because it's bundled software, and I can't get through to Wacom.  Thanks!
