Can’t Build Playlist Without App Crashing – Brainwaves -- Binaural Beats Review

As soon as I hit +add recording, it crashes every time. Very frustrating. Spent a lot of money on this app and used to enjoy it very much. Have severe insomnia and the playlist was very helpful. Now half the list is gone. This issue has been happening for well over a year. In April I was told the developers were working on it and have it fixed in no time. It's July now and I'm just frustrated. A lot of money invested here while still unable to utilize main functionality. Do I need to delete and redownload? Will I lose everything I've purchased? Please advise.
