I have had my CE5000 about 8 months and love it. I am going to admit to a mistake I made with mine and maybe it will save you some grief. When I installed the cutter I didn't realize that the installation process created a USB port for the printer, so when I connected the cutter to my computer I used the standard USB001 port, not the Graphtec USB port. I was having some communication errors and about to pull my remaining hair out when I happened to scroll to the bottom of my availble ports list and found the Graphtec USB port. Choosing the Graphtec USB port has all but eliminated the communication errors. Best of luck and I hope that you enjoy your cutter as much as I have enjoyed mine.
