Yes, at one time I deinstalled the app AND thorougly cleaned up all folders involved. I did that while I was debugging issues mentioned in my other posts (now all resolved). So, it was a plain mistake on my part to not save demotrades.csv before the cleanup. Usually I just install over the previous installation as you suggested.

But, I won't cry over spilled milk, I learned something, life goes on... yadda... yadda

And BTW, I don't see compatibility folders come into play anymore. I don't know if that's because you made some improvements to the Zorro, or I accomplished something with the clean install. Anyway, it's nice to see all files where one expects them to be.
