First, Correct Reference is a PC-only product, if you are on a Mac, it won't help you. I went from 4 to 4.03 without a problem, and then up to ProPack easily... and I moved jillions of files between machines and formats, too, but my Mac tends to be well-behaved. Alloting memory and such stuff is easy. I do have problems with MAT files and things relying upon them, since I keep as much as possible outside of Runtime, including textures... but that is my choice. Note: occasionally an rsr file in the Geometries folder can get corrupted. If you are only having problems with Mayadoll and her clothes, rather than widespread problems with hundreds of files, I'd check that particular file before doing a full-fledged reinstall. Since conforming clothing often references the underlying body, I'm suspicious that the model herself has a snag. Carolly
