Pro problems

As some of the reviews I am having an issue with pro. I bought the app so I can convert some of my windows videos and save them to my apple device. Still having troubles and the app is telling me to update to pro when I already have pro. I have been having issues with this app for a few years with no insight or help inside the app. Not a good app to promote to others
