beaTunes is not designed to open individual files, it is meant to manage a whole library. When you first started it, you were asked to specify a base folder, under which all your music files reside. Then beaTunes read data about all those files and displayed them in the main table. When you want to analyze a file for tonal key, you have to select it in the main beaTunes table and choose analyze.
Is the problem perhaps that you cannot find your files in that beaTunes table? Not even with searching? Perhaps you have given beaTunes a base folder name that does not contain your music files?
