problem!

I really like this app. I enjoy tapping away to cnblue but I seem to have come upon a problem. It seems that everytime that I open up the app and choose a song, it shuts down. I try to get back on and it does the same thing. I tried to delete the app and re-install it again but it kept shutting down. At this moment I dont know what else to do, is someone else having this same problem? and can it be fixed some way?
