couldn't you just remove the sea Hurri's mod folder, and delete its profiles in air.ini, planes.ru and weapons.ru

If it has an entry, it'd find it (eg seahurriIIb or something, i haven't installed it yet myself). Make sure you have the latest aircraft installer 3.6, and if it still doesn't work, like i said, you should delete the mod folder and its entries into the 3 above named documents. If you're not sure where they are, ask, and i'll post their locations.
