[GW-Booksense] I am in big trouble-HELP!!!

[DIANNE B. PHELPS AND PRIMROSE]

If anyone is out there right now, I just tried redownloading the Beta 1.1 
firmware for the Book Sense XT. I extracted the files to the root directory 
of the SD card, but now, for some reason, I can't get my computer to release 
the USB mas storage device as I can usually do. Can anyone help me 
troubleshoot since I don't want to just pull it unless there is no other 
way.

Thanks so much for any help anyone can offer! Smiles!
