I was having the same problem as the rest after hooking my RCA S2001 MP3 player up to my new computer that is running Windows Vista Home. I did the following to fix my MP3 player on my old computer which is XP Home.
I fixed my player by loading the latest firmware version (1.5 at this time and can be found at http://www.rcaaudiovideo.com/product.aspx?product=124&post=6 ). After you load this application to your computer you access the update device application from the start menu/programs/RCA digital Audio Player/Jet/Update device. One thing that I had to do that had not been mentioned yet in this forum was selecting "Format data area"

Doing this wipes your device completely clean but it allows for you to keep using the device. The update device program will give you additional information after the update and format.
This should fix your device if not contact RCA through the same website above to ask additional questions.

Maybe try using your sisters USB cable I did that once and it idn't work at all.

hold your on/off button for 10 seconds

I had this very same problem. To fix this problem you have to re-flash your RCA MP3 player with the following file: http://download.rca.com/download/RD1022_28_72_76FWUpgrade_v1002.exe My RCA Model RD 1072a as worked fine since flashing the player with this file.
