The reason people are encouraged not to use the animeditor is because it is buggy and I think it was the horse animations that mucked up. Best to trust Vercengetorix and use the XIDX to avoid problems, it's still at quite a basic stage at the moment so not really made as user friendly as the animeditor was. The XIDX is still pretty simple though once you get round all the file path stuff, there just seems to be more room for error.
