Parallels and Bootcamp

I installed Vista Ultimate under Parallels Virtual Desktop on my mac and
activated it.
Then I installed it under Bootcamp on the same mac and now it won't activate.
Should i use the phone activation system or call them.
Call them at which Number. I'm in US

The license is for one installation. If you removed the Parallels
installation, telephone activation should work, If you haven't, you will
not be able to use it after getting Bootcamp activated.
