The .rgssad file is a database file that contains most of the games data. It's not a patch in the traditional sense, as there's no need to run it, extract it, or do anything special to it. Simply place the file in whatever directory you installed Laxius Force in.
(As an added note, you should already have a .rgssad file in the install directory. You need to replace that file with the one you just downloaded from the above link.)
