Hey Tim, if you're still with us here --- That version of SignBlazer is 'abandonware' of sorts, with no activation required anymore.
It's like a can-opener for getting up and running most any cutters with USB or serial DB9 cables , however it's uncirculated as an optimal software option anymore officially from USCUTTER.
Rightfully so, but there it is.
VinylMaster is the topic header, and I apologize for interjecting SignBlazer once more but I just had to, the fact remains Jerry Bonham exists for us all. What we are able to do in the world of sign making, and getting maximum use (and resulting $$$) from the products sold by USCUTTER, that knowledge for many of us out here all comes directly from Jerry's tireless efforts, prior to his death.
Search "Jerry Bonham" for insight into that distant past of these Forums. It's out there.
