Null(0) : photos won't show (has nothing to do with authorization) IPad 2 to PC

So today I was trying to transfer pictures from my iPad 2 to my PC with the newest version of this app.However, after I clicked "discover devices" , no photos or albums uploaded.Instead, the text "null (0)" appeared, with "loading images" appeared on the button. I know this has nothing to do with the authorization,as I have tried authorizing and re-authorizing it on my iPad. So now I am unable to upload images to my computer.So I checked my wifi connection, but there seems to be no problem. I tried the online method, yet it could not seems to locate my photos either. I tried dragging the windows, and that didn't work either. Also tried uninstalling both the app on the computer and ipad,but to no avail. As a lresorption, I tried resetting my ipad, but that didn't work even. I love this app and would like to get it fixed again.Help or advice would be greatly appreciated. Thanks in advance.
