Re: Disable save in player pro

The issue I was running into with editing was the cache, and John's
suggestion of deleting this in the text editor worked for Mathematica, but
not for Player Pro.

It seems that if there is no cache Player Pro will not open the notebook.
Have others had the same experience, or is there another reason it will not
open?
