I see a window and then it crashes. I have tried 32 and 64 bit versions with same result. I see files from the library I had in Version 10 app that was working, even though I have uninstalled every version I installed. I have solved the issue however based on suggestion posted in forums. Changed WaveformType from 6 to 0. App now starts and appears to work except that whenever I try changing skin or appearance it crashes and the large waveform does not appear. This is specific to the laptop I am using. It loads and works fine on other machines. But unfortunately the one I need to use this weekend is the one it won't work on.
