Help!! – AUM - Audio Mixer Review

I love this app to use with my iPad but now it stopped working and says the audio engine isn’t on. I’ve uninstalled it and reinstalled and still have the same problem. Is this an iPad issue? GB and Cubasis 3 and the other apps are working fine. Any suggestions? Also, I wanted to contact you on the website but it says it’s not secure???
