e250/Vista file reading issue.

I have just got a new HP with Vista Home premium 64bit and it is giving me trouble reading the files. The e250 player is working fine otherwise (v4.01.08 firmware) on my old comp. When I plug it in to the Vista machine it does recognise the player, but only shows the "recordings’ folder that is native to the player. I had 2 other folders for Podcasts and music, but they are nowhere to be seen. The space taken by them is accounted for in the disk space usage counter, but is referred to as “dedicated music” and I cannot access it.

'Sup with that? Any hints for me to rectify this?
