Ok, when I first started doing small model edits a while ago I had no problems with it, but now I've recently come back to do them again and whenever I try to view for example a creature model, no model shows up, the animations dropdown to be a list of "Unknown" tags, and the model skin says there is "No Skin Found!" I don't know what I've done wrong, help would be greatly appreciated, thanks.
*edit* I'm using MyWarcraftStudio 0.10.6337
