What can be the problem? ~Clothing meshing.

[Nahishooka]

I followed NeptuneSuzy (http://www.personal-computer-tutor.com/sims2/suzysclothingtut.htm) step by step. I'm quite sure I did it all ok, I even done it twice, on two different meshes. And yeah, I'm 100% sure I've replaced the Geometric Data Container..
The problem is the changes just aren't shown in the BodyShop! Nothing! I'm still seeing the original maxis mesh I've edited.. what went wrong? :(
~Note: right before I'm exporting the mesh, I'm getting this message -> http://img826.imageshack.us/img826/9387/45774448.jpg Maybe it's connected to the problem?

Thanks in advance. (:

Don't use that tutorial. That is a very old tutorial using old methods - there's easier ways! Use the Unimesh 1 tutorial in the Tutorials area at the top of the forum you just posted in.

Thank you! I wasn't awere of that shortcuts!
By the way, eventually, it has shown up, but totally crappy;
But I'm trying to do a new mesh now in that method, so thanks. (:
