Jimmy, if I were facing a serious support issue, with ANYTHING, I certainly would not be sitting around for two days just hanging by the phone for a tech. I've never encountered any problem contacting USCutter personnel, just keep in mind they are on the west coast.
(425) 902-1302
(425) 902-1305 (main #)
(425) 481-3555
Fax: (425) 284 3169 (yes, using the Fax number is an alternative way to send an urgent message !)
==================================
So far, this is what we know --- You own an SC cutter. It doesn't communicate with your computer anymore (since an update within Windows).
Let's get some information about how you have the SC connected to the computer? (USB or serial)? Do you know how to go into your computer settings (hardware & devices) and verify the PORT access? Have you attempted to run the cutter using SignBlazer? If not, why not?
C'mon Jimmy, this ain't rocket science. Just give us something to work with, and we'll see what's what.
