i bought sketchbook pro last week for my sisters bday and finally got around to getting it installed on her computer tonight.  got it installed really quick and clicked to start it up and here’s my prblem… where do i find the serial number and product key?  i see numbers along the barcode at the bottom, and unfortunately the sticker along the top portion of the back was scratched off and i fear thats where the serial number was… there was no booklet that came with it or anything, and it pisses me off that i cant get it set up.  im annoyed enough that i refuse to click the 15 day free trial bc we will be back where we started once the trial is over.  any help would be greatly appreciated, thank you
