All that seems to be in order, my RTW and BI work stand alone and so does my EB without any of the downloaded add-ons. The problem seems to be exactly how I'm downloading these mods and replacing the files: I delete the files with the same name (EBBS script and descr.mercenaries, etc.) and "extract the files" from winrar "to the specified folder", i.e. where those other files existed previously (I've checked, I'm putting them in the appropriate folders and deleting all my map.rwm files). Is this all kosher? What should I be doing?
