try removing then reloading software for the studio (ensureing it's the right version for the phone) check your usb cable works on both phone and pc end. you should be able to go into file and then CONNECT and it should allow you to connect with your phone automatically then follow the menus. To move stuff to PC click TO PC option and visa vers for stuff on your computer. 'Drag and drop' should also work with this.
Is you computer bluetooth? if not try buying a bluetooth dongle and software from samsung direct and try loading that.
Hope this helps
