Store mode on hyperion duo ii question

ok guys an update. i went to try to do the update tonight and ran into troubles.

I downloaded the driver and installed it and got the latest revisions. when i started the update, you have to switch on th epower before i gets to 100%, and when i did this it sent a error message saying id device not found. has anyone else encountered this problem? is there something im doing wrong? i read the manual up and down over and over and still no luck. i was about to try having the power on and then starting the update however i figured id check here first since the hyperion site has a pretty specific order of things it seems. any help would be greatly appreciated.
