I simply can't get any sound out of the bookport. It was not working properly even before I tried to update the firmware. I thought it might be the complact flas card, but the computer recognized the contents of the card without difficulty. I tried to reset the bookport but was unsuccessful. I took out the alkaline batteries I had in there and replaced them with another set of alkalines but nothing helped. I hadn't tried to update the firmware before this point. When nothing else worked, I attempted to update the firmware and mistakenly replaced my alkaline batteris with rechargeables. I hadn't read in the manual that this was a no-no. Did I fry my unit? Is there any other option besides paying for a new bookport? Please help! I will be so lost without my BP. Tai
