Android File Transfer not recognizing phone

The AFT app isn't recognizing my DROID RAZR M. I deleted the app and redownloaded it, but nothing changed, if I plug into my phone it does not open automatically like it used to. I will then open the app manually, and it tells me no phone is found. What do i do? I'm on a mac running the latest software.
