I have a Promethium ActivBoard 300 Pro which when you plug in the USB it goes through the colors and turns white for about 45 seconds and then goes flashing red flame. I have replaced the laptop it was hooked into, updated the drive (win x64) updated the software, and replaced the direct USB cable. is there anything else I can try? I was unable to find a firmware update and how do you locate the serial number? Thanks We have 50+ boards at our school and just love them.
