Great! I want to thank hauangua for that link too. I had forgotten that post, and was about to go through another full explanation, which probably wouldn't have been as good.
The reason I asked about your labels is because I have several downloads of earlier versions of the MFM, and some of the skin packs have the proper date labels on the folders but at least one other has them with labels like "MFM-v3-US+UK_Skins19390901", which won't work unless everything is removed but the date. I just wanted to make sure that I knew which labels yours had so I could describe what to do next.
