[BCAB] BOOKSENSE QUESTION doreen.tyler 24 Nov 2012 13:40 GMT

Hi everybody:
Hoping there is a proficient BookSense user out there.
I have an American Booksense and am trying to upgrade the firmware, currently I have version 1. I have I believe an xt model as it does have radio capability but on the hims site I also see mention of a BookSense SD.
I have tried to upgrade the firmware to version 2.1 which i downloaded from the comproom.co.uk site but when put onto the root directories of both the flash disk and the SD card, is not seen by the BookSense, though it is by my desktop computer.
I am at a loss to know what to do next. Any help at all would be appreciated.
Many thanks.
