conundrum connections.....

ok, so i have spent the bulk of this day trying to figure out why i cannot seem to synch my pda, nor add more of my mozart lectures to my expansion card...at one point the device wouldn't even connect with the usb port......and after uninstalling and reinstalling and consorting with online help....i have successfully brought this conundrum device back into full usefullness......i did manage to walk 2 miles.....but that is all i have done since 10 am......tech may be the thing of the future, but techy things bring with them great anguish......
