Lost 5-6 hours of work because of a serious problem with the App

(I have an iPad 3 with latest iOS.)
Because Image-Line has no easy, helpful way to get tech support, they leave me no choice but to write a negative review.
I just bought FL Mobile and lost the 2 files I made when I "saved" them! It just stripped all of the data from the files instead of saving them. I also cannot create a new song. The button is unresponsive.
I obviously cant continue to use FL until this problem is acknowledged and fixed.
But, honestly, this is not much of an app for $20, anyways. It seems designed mainly to get you to buy very high-priced IAPs. I was shocked at the prices.
