Not wanting to necro an old thread, but: I had this problem with 7.6 on Vortex and I tried every fix mentioned here, putting the files in the same folder(s), making sure of the file pat,h making sure the correct files are present. Nothing worked. I tossed 7.6 and installed 6.1 and it worked instantly. Well, instantly after rebuilding the animations once. So something might just be iffy with 7.6 and Vortex.
