Uhm. – InstaVideo Pro - Add background music to videos Review

I got this app, and I paid for the pro version and after two videos it won't work, it says "error exporting, please try again" and I have but it still doesn't work. I love it but I'm sad that it won't let me save the videos anymore, even though I PAID for it. :(
