Just does not work

This was supposed to be just the perfect player for my soudcloud playlists… but it doesnt work.
After instal, when i click on the icon, nothing appens.
Tried to switch off/on my computer, but no, nothing appens.
My computer is on iOs 10.7, so it is not a compatibility problem.

I want to be refund for this app.
