I have two songs on my PC that I want to transfer to the H2. I have them saved as *.mp3 and *.wma files. When I transfer either of them over to the H2 they are listed in the appropriate folder, BUT when I try to play them is says INVALID FILE. I've tried to check the bit rates and samples rates and they seem OK, but I'm not really too sure. I've gone back to the manual and there is very little regarding transfer of files.

Can anyone help or recommend something?
