really liked this app... new version crashes

I used to use this app all the time. It may have not been perfectly accurate, but I used to to get ideas for painting.
The new version crashes constantly. Maybe it works on a newer devise, but regardless its incredibly frustrating.
I hope the app designers read this... please, fix the app! that, or allow us to revert to the old version.

crash :-( about PANTONE Studio, v2.0
