I made another mistake in the article. You should make a copy of Broodat.mpq named Patch_rt.mpq, not rename it. It's been so long since I've actually used this procedure that I forgot some things. Now everything is fixed.
I just recently found that the Mpq Control doesn't work on some system configurations. It doesn't even work on mine anymore! If you have problems with it, download the mpq2k version. It doesn't have any problems. (to the best of my knowledge ;)
