Try rebooting the pc and phone

New phone? New SD card? You may need to format the SD card IF you haven't yet. Don't blame me for losing anything you didn't bother backing up.

The same is happening to me too. The weird thing is, it was working fine 2 days ago. I've rebooted my phone and computer several times but no luck.
Please help...
