You still have WoD models. Error is most likely caused by the launcher that you have so you can either:
1. Delete WoD models which will then use the classic ones (http://forum.warmane.com/showthread.php?t=383205)
2. Redownload launcher (with old models also)

If you don't want to get rid of new models, maybe try deleting cache folder from WoW, setting it to run as Administrator under right click -> properties and maybe applying Large Address Aware. Those are generally the only options you can do.
