I have a FP3 Fisher

Question

I have a FP3 Fisher Price player. We were able to load music onto the player when we first bought it. Now (6 months later) we wanted to load additional music onto the player. However, when we connected the player to the computer and have the program on the computer running, the computer recognizes that the player is connected, but the program keeps saying it's searching for the player. After 2 hours of trying everything we could, I gave up! I spent $60 on this and would like for my daughter to be able to use it. Thanks.
