They should be totally differnt files. Make sure you are opening the correct one? If you have multiple of them installed, check the file size, and use the bigger one. Or uninstall the free one first and re-download the paid version.
It works on my computer, yes haha. When you say blurred, are you just looking at the scene select screen? You will still have to go unlock the scenes by playing the game until those become unblurred, even if you played the free version.
