Very disappointed right now

Everything was working fine, ive put very much money into the app, Ive made countless beats with it, until today, i downloaded the pack with the horns, strings, etc on it and now my app refuses to open for me, countless beats i had in the works or completed, now gone. Very upsetting, hopefully an update can come out soon that fixes this, until then I am showing this app only 1 star :(
