what?? sent it back??? you don't have to send anything back... the 8r07 is a downloadable update from diabo's site... you download the file, hook up the predator to your computer using the PC interface kit (power supply and serial cable), download the software and instructions, and then update the predator by loading the 8r07 file into it.
I hope you didn't ship it back to someone??? D'OH!
