Video no longer functional

What happened to the video and transport controls?!! After the last update, this app is useless to me!!! Ive spent over $100 on in-app purchases for video tutorials and now there is no video - even deleted the app, reinstalled and re-downloaded with the same results. I havent received any response from the app developers either. I feel ripped off!!! This used to be a very useful set of tutorials.
