This happens pretty frequently when a classic mod is ported to gold. The allowable target types are different. What usually happens is that there is a space hidden before or after the text in the target type, or the \ is entered as a /.

Open up the "components" file in the data directory, and scroll down until you find the entries for anti-ship warheads. Make sure there aren't any blank spaces after the entry "ships\sat" (and make sure the slant is \ and not /).

That should fix the problem. If not, check back in the SE4 forum, and tell 'em grumbler sent ya!
