CLARINET QUINTET in A major KV581 + Online Audio

This is the first time in about thirty years that I have been unhappy with my purchase, and it is not JE's fault. I had a Peters Edition of the clarinet part with Piano accompaniment which came with a CD of a professional string quartet for a backing disc. Naturally I got it from JE. I lost the CD recently and wanted another. JE advised me that there was no longer a Peters version and offered me a Hal Leonard one. Reluctantly I bought it as it is an online version to download. It was impossibly quiet on my laptop and on my wife's tablet. I put it on a USB and played it through the TV. Then it was loud enough to play with, but no matter what, I could not download the movement in the right order. III kept coming up before II. It doesn't play them one after the other either. You have to find the movement and click it on. This is supposed to be progress, but it has made my two different types of CD player obsolete, and I can't carry the TV about with me to play anywhere I like, and if I play it at home, no-one can watch TV. Once you could just buy what you wanted. Now you have to accept long Terms and Conditions (non-negotiable) and can only buy what the cash swallowers deign to sell. I shan't abandon JE, but Hal Leonard? Don't tempt me!
