Doesn't work. Don't pay for it. – Video lab - free video editor movie collage photo video editing for Vine, Instagram, Youtube Review

I downloaded the free one and it worked fine. I loved it so I paid for the Pro version and it doesn't work. Kept telling me "Cannot complete operation". So I went back to using the free one and now it's saying the same thing.
