I have a laserpoint 3 cutter that I bought a couple of years ago. It was purchased brand new from us cutter. I hardly used this machine, and after my PC was stolen at Christmas last year, I put the cutter in the closet, covered until last week. I got a refurbished laptop with windows 7. Reinstalled vinylmaster pro edition. The program loaded fine and the cutter cranks up and seems to be problem free, however, I cannot get it to accept anything from my pc. It says usb ports not detectected.detected. I've checked, my ports are working. I've changed cables and now am leaning towards a null modem serial cable . Any ideas?
