I can't use my Fuze!

Someone please help me, I need some advice.

I just bought a Fuze, I used to have a much simpler Sensa…

Now, I can’t play music on the Fuze. I’ve downloaded the files, everything is fine up to the moment I select a song, it does not play! The green play symbol is there, there is 0:00 on the left hand side, and -0:00 on the right hand side, but there must be something I do not do properly, I cannot have it play the selected song!

Can someone please help me?

I tried to change the USB mode, it didn’t work either.

Thanks in advance.
