? – Slow Down Music Player Review

It was a great app for a good couple of months I had it and now all of a sudden, the slider bar is missing... The last update this app had was in 2013. If y'all can fix this problem, that be fantastic!! I had uninstalled this app many times once this started happening to see if it would fix the problem but sadly it hasn't.
