Digital BW, The Print

Hello all, I wonder if any knows how to move the power retouche 
plug-ins from one computer to another. I just moved my photography work 
to a different computer, including photoshop CS. I moved the plugins 
folder also as well as the power retouche folder in the application 
support folder under library. When I run the plugs, it tells me that 
they are not registered and to run the installer again. I emailed the 
power retouche, and they are out of town for a month.
Any ever done this? Thanks for any info..Doug M
