idk! i recall on my old machine that they were just kind of there in the folder with the app. no - i'm not stupid, i always thought that was jenky too. maybe i missed something. where are yours?

Did you tell it where the data files are? Is it up to date? If you have a bunch of drives the drive letter can get changed...maybe View>preferences and settings>data folders

im on a mac, and it won't let me get past the authorization/would you like to install data (already installed).

Yep should be in the same folder as the app.
