yup. Bones aren't too hard to use - in fact I think they're MORE versatile because it's for example easier to make things that are near-perfect mirrors for example. Like stated, you get the rotational motion that can't be had through morphs because morphs are simply "point A to point B".
I also won't fail to mention that the Sequence editor is a marvelous tool to simplify the process of repetetive animation that just isn't known to morph targets.
That sounds pretty freaky, by the way - the error. I've had some BIG issues with older version of Anim8or when trying to use morphs and then editing the object afterwards. If anything, bones gives a LOT more room for error when it comes to having to edit meshes and stuff afterwards - more flexible in that sense.
Good luck!
