Ok so I've successfully archived my .mc6 files and imported them into poser. I've also tried turning them into MAT poses as per the tutorial which I linked to in my first post in this thread (changing file ending to .pz2 and version number in the code to 4.01)

When I unzip the .pz2 files into poser, the files go into the right place in the library (pose category) but when I double click on them nothing happens. Any idea why this is? (the .mc6 files work fine)
