iTunes really does not deal well with manual file renaming. If you like iTunes and really want to use it, you're better off not renaming your files (... and why would you? iTunes never shows you the filename).
However, not everybody likes iTunes. If you want to keep on renaming your files manually or through other software than iTunes itself, you need to embed the data that beaTunes is calculating in those files - otherwise you loose the 'connection'.
To do so, go to the beaTunes general preferences before you analyze any files with beaTunes and check that 'Embed non-iTunes fields' checkbox. That will make sure that beaTunes writes results not only to its internal database, but also to the files themselves. If you now move/rename the files you can ask beaTunes to import data from the files (there is an Analysis Task for that). That was you don't have to recompute them.
