Good but needs a little fix up.

When I first got the app everything went well with it. It was very good and it helped out a lot in making the edits I do. But something happen to it and it could have been a update. Everytime I need to download a video it freezes and Im forced to leave the app. But it continues. I dont know whats with the downloading thing but its stoping me from my work. Please find a way to fix the bug or glitch in the system. Much appreciated
