App crashes after 2 or 3 mnutes.

I am using windows 10 and this is my first time on Jamkazam.  After about 2 or 3 minutes the app crashes and I have to start over again.  Am I doing something wrong?   Also, if I close the program, the app disappears, and I have to start over again.  THis shouldn't be happening.
