Help usb connects but only shows shortcuts


Hello all

I'm using the htc desire z

my phone will connect to my pc with the usb cable, will charge, and even shows up as a usb device.

however when opening up the folder to view the phone, all i get is shortcuts all with a 1kb size, none of which do anything. I am unable to add files to the phone or to get into folders on the phone to move files like pictures from the phone to my computer.

The connection used to work, just stopped about a week ago. I have done full virus and mallware scans and both the phone and computer are coming up clean.

If anyone has any advice on how to get it back so i can transfer files back and forth between my computer and phone it would be appreciated.

Thank you
