Hi, I recently bought a new CT630 plotter but can't seem to get it to work. I've tried the whole SignBlazer thing but it only worked a day, I also have FlexiSign got it to work on that on the same day but the next day it was like the plotter didn't even exist. I've watched the set up videos and to be honest I've worked with plotters, large format printers and routers before but this is a first for me. I've tried it on XP, Vista and 7. HELP PLEASE! before I send this back.
