Every single time I switch the HFS+ driver forgets it is registered. Boot into Windows: register. Access via Parallels: register. Boot directly: register. Access via Parallels: register. Repeat forever. I must have registered the blasted thing a half dozen times already all on the same physical machine.
Windows, Microsoft Office, and a few other programs I use are smart enough for their registration/activation to survive switching. But not the HFS+ driver.
