Philips Go Gear MP3 player 2 gb SA 512...

Hi,
Three hours later, I'm still trying to get my Hp Pavilion with Vista to connect with my Philips SA 5125/37 MP3 player. It used to connect to my old computer with XP.
What I have tried: Re-installing software. However, when I connect the device to computer It searches for preconfigured driver folder which it says was not successfully installed
and then says MTP device failed
Called the Philips people who said this device is compatible with Vista, but wonder if i need to install an updated driver from Philips? or Windows? or somewhere.
Can you help. Thanks.
