After purchasing ireal b for my Kindle Fire, I was playing around with the program without reading any instructions. I modified a couple of the blues exercises to match lessons I'm working on. I renamed them and saved them in a practice play list. In doing so I think I have lost the original exercise charts. I wonder if there is a way to recover the original charts. I'm guessing the way to keep the original is to modify a duplicate copy. Any help or advice would be appreciated.

Thanks, Jack
