For the people having trouble with the cc06 in combination with this patch, try this :
make a copy of your eng.db and rename that copy to brp.db and then copy it over the existing brp.db (take backups first), Open your CC06, and you shouldn't have any trouble anymore.
Then ,after each edit you do inside cc06, and save, export brp.db to brp.mdb with UniDB 4.0, then import brp.mdb to eng.db, and everything works ingame also. Sounds complicated? It's not, I did it before in Fifa2005 where I made several custom leagues cohabit, patches and self created teams and everything went fine.
Note : substitute eng.db with your language file if you use your Fifa06 in another language
