If you've not figured it out by now...
I would suggest forgetting the raid module for AoC's use. The module was designed for AO and used a unique feature of that game which was the ability to create ad-hoc chat channels (in AOC you're limited to using the pre-defined channels provided by FC such as global, guild, tells and so on. In AO you could create your own) In AoC you can't create ad-hoc channels so the raid module can be a right pain to use.
It DOES still work but you'll have to use guild chat for announcing. It's also not designed for AoC's bosses (though I did re-write mine for AoC's use - I should release that actually) and is a little "clunky" in use.
