I'm currently working on the free character modelling tutorial, and I'm at the part where I change from polygons in to Sub-Ds.

..I get two problems though.

1. When I convert it into Sub-D, it splits each finger into three parts, so my character ends up having 10 fingers on one hand. (Three rows of three fingers stacked on eachother, and the thumb)

2. I was messing around trying to fix number 1, when my model went nuts...
Now it looks like a mix of Sub-D and polygons, with a bunch of loose lines running rampant.


...and now updated with number 3: Somehow, the shading completely dissapeared, leaving me with just the mesh of the character...and hitting "5" or "6" doesn't do anything.
Neither does Ctrl-Z

Edit: I forgot to add something..
When I first tried converting it, it wouldn't let me, saying I had to clean up the nonmanifolds or something, which I did. Maybe that is the cause..? I have no clue what nonmanifolds are.. :/
