Hmm, I'm not very experienced with animations and such, but I don't believe order is an issue, as long as they are in the folder. Try making sure you don't have duplicate or missing files, and check for duplicate particles that may be causing your game to crash.I have no meshes or particals [besides the originals of course] and nothing missing, I can go into the FH Preset maker, but only on feline, when i switch to canine [which is the file that is messing up] it crashes.
