Need Help Gerber Edge Won't Initialize

Hey gang---a colleague (she had submitted to join, but has not yet received acceptance from admin) is having trouble getting her Edge to a state of "being initialized" and ready to accept jobs. They've used this machine for years, and then one day upon start up, got a "data error" message (on the machine's display). Next step?...they replaced the parallel port cord = same result. Next step was to try a parallel to usb cord. With the new conversion cord, they now get "code 15326424"...with the "24" toggling back and forth from "24" to "23". Machine powers up, but with either cord it won't initialize itself to be in the "ready offline" condition. Any ideas?
