Crashes and unfair business

Bought the old version and it worked fine. Suddenly after i Upgradede my Mac, it did not work and I had to buy the new version for full price, no rebate for upgrading.
Ok, I needed the tool and bought the new version and installed it. It does not work either. I am told to remove some Quicktime files I dont even have.
I needed this tool now and it just crashes. Big dissapointment!
