I’ve had this problem once before, with Windows XP. Apparently there is some kind of wierd but going on. 
What I did was this…
Go into the device manager and right click on the player, and select “Update Drivers”. Browse for drivers manually, and you should get to a screen that shows compatible drivers alread (pre)installed on your system. Select “MTP Device”. Click next, and wait for it to install the drivers. *Hopefully* this will make you computer recognize the Fuze+, and you can use it just like before. Why either of us needs to be put through this process is beyond me.
Please note that if you ever connect any other MTP devices, you will have to repeat the same process, assuming it worked the first time.
