Error - 8709 cdj 2000

Hey guys,

I am getting the "Error - 8709 communication error" and also that little cirlcle that says "WAIT. Is there any hope? It won't even read my thumb drive for me to do any updates or firmware. Any suggestions? Thank you in advance.

Haha I just plugged it back in and waited a half hour and it seemed to fix itself. How funny! No more circle saying "waiting". I didn't even have a screen. I really don't  understand how this happened in the first place but from no screen to that circle saying "Waiting" now It's reading my thumb drive. WTF? How odd is that? Anyone have an answer to that?
