ANDROID Need advice and whatever

I just upgraded my Samsung s5 phone from Lollipop to Marshmallo 6.01. Model number SM-G900V. When I was checking my apps and got to Primo 2.4 I got an error message and it wouldn't start. "missing or incomplete folder: /data/data/com.nng.igoprimoisr.javaclient/license". Any ideas how to correct that error?

Also, my phone [internal and SD card] no longer show up in "MyComputer" although the phone shows up as being connected via USB.
