Removing the Faces Megapack

I had the faces megapack installed but it caused my game to lag quite considerably so i have now removed it but it has also taken away the original faces that were on there and also the blank grey ones. Any ideas how to get them back?

Many thanks

Figured out how to do it now. Sorry for the trouble

It doesn't cause the game to lag at all, so it was a bit of a waste of time removing them. It does make it slower to load when you first start up, but that's all.

Well for me it just seemed to cause it to lag that was all
