Audition audio Input volume becomes lower in session?

I'm new to Audition CC and just started using it this week.  I have RODE Reporter mic commected to the laptop via usb cable.  Everything was working fine for about a day and a half.  After I came back from lunch to continue recording the input volume was very low, nothing like the morning.  No settings were changed.  I spent about 6 hours with adobe help driving my computer and no help.  We loaded ASIO drivers, no luck.  I'm open to any all ideas you may have.  Thanks in advance for any assistance.
