I've had my Treo for about 4 days now, and already I've had some problems with the 128mb SD card!!! I think my problem may have come from an application, MyCheckbook 2.0, but while using it I did a back up and got a "fatal exception" error. This resulted in a hard reset and the lost of functionality of the SD card. I'm sure it's the card because the Treo's fine, but the card will not be recognized, or formatted by anything, the Treo or my desktop or laptop. I'm running XP Pro and WinME and neither will see the card. Has anyone else had this problem??? I think it's time to replace the card?.?.?.. Help
