Hi Gang..................... A few years ago I bought a used computer and a bunch of soft ware. In the software was a disc for PS 5.5. At that time I knew even less than I know about computers than I do know(if that's possible)[grin] My buddy came over and installed a number of the programs including the PS 5.5 program. I understand that if I wanted to up grade to PS 7 I would need a License or ID number of the PS 5.5 when I went to install the upgrade. I looked on the disc and found a serial number that starts with PWW55OR followed by seven numbers a dash and then three more numbers. Can anyone tell me if this is the License number I need to have if I want to install an up grade? Thanks Russ R.E. Baker Photography rebphoto@pronetisp.net
