Cannot See Pics When Connected To Computer

[pbmac]

Hi,
Normally when connected to a computer through the USB cable I see:
Computer>Samsung-SM-G900V> and the some other options ( can't remember them now ).
I would navigate to Card>DCIM>Camera and be able to see the pics there.
Now all I get is: Computer>Samsung-SM-G900V and nothing if I click on it.
Any help would be appreciated.
Thanks for your time.
