Help with animations

I was making an animation in Image Ready, and when I went to "Save Optimized As" it wouldn't let me save it as a ".gif". It lets me save it as ".jpg", which, obviously, isn't animated. It also lets me save it as "html". I'm doing everything the same way I always do it, so I'm thinking maybe it's an IR problem? Or maybe not. I looked in the Archives about saving files, and according to them I'm doing everything right...it's just not working. Anybody ever have this happen to them before?
