Why is the sound speeding up now? – Vizmato: Video Editor & Maker Review

I bought the app and paid to get rid of any ads or watermarks, but in a recent update all my videos are speeding up now. Why? Please let me know when this changes back, and I'll happily change my rating. I can't use this to edit any of my music postings anymore because of this problem...
