The other reviewer who said this app has problems was right but is no longer. I had similar problems and after getting over being mad contacted the developer thru his website and he sent me version that fixes the problem I had and the problem the other reviewer also had. I am happy to say that the developer of this app cares about his app and the users of this app and has fixed the problem and made other improvements. It his app rocks and I will use it at many live events! I recommend buying this app
