ok... I moved the file into my default library and it works. However,
I'm trying to work on a lot of fits, that are all in a folder to make
my life easier and more organized. Should i make that my default
library then? and move the library that is currently my default to
just another library? Having it as a folder inside the current default
library also causes issues
