I have an iPhone 4 and recently I am unable to access my photos on my PC. the problems are:

  1. the iPhone is recognized as a device but camera wizard won’t let me extract pictures as if there aren’t any.

  2. the iPhone keeps asking me again and again whether I trust my own PC even though I always press trust/yes.

I have tried accessing the pics from another computer and it worked, but on my own computer, I have tried replacing the USB cable, removing the cam wizard, and restarting the computer without the device. Nothing helped.

I would really appreciate you assistance :)
