Ok. I'm having a bit of a problem, and I'm curious if anyone else has had this happen to them. I decided to do my first "backup to usb" today, on my Premium Vault. Every time I attempt it, it makes it somewhere around 25% done, and the display blinks a couple times, and it exits the service mode and straight back to as if I had never opened the door and went into the utilities. The machine doesn't appear to do a total reboot, just completely exits the service menu and backup procedure. I was doing a backup hoping that it would save our high scores and settings. Unlike the Spike systems, there's no utility to save settings and scores, just total backup, so Im not even sure if the backup will save the things I want it to. Please let me know what you think. I'm going to grab a new USB stick and try that tomorrow. Ive already took this one, reformatted it and tried again. No difference. Its a 4gb USB stick.
