Well, as some people may know, I use 3ds Max mainly.

I'll start this off by saying that I have very very little experience with UV Mapping.
However, I have moved faces around in the Edit UVW's window with no problems before, so I have no idea what's going on.

After I've added UVW Mapping and Unwrap UVW modifiers to my object, I adjust the mapping using the gizmo in the perspective viewport.
However, when I open the Edit UVW's using the Unwrap UVW modifier, and select more than 5 faces, it freezes.
Either that or it lags tremendously.
Which really stumps me, as usually, 3ds Max runs at a steady 375 frames per second. And this worked perfectly before.

Anyone who has experience in Gmax can help me as well

So with that said......... any help?

EDIT: Gaaah, now Gmax does the same thing, except it outright crashes! If this persists, I'm probably going to have to resort to reinstalling them both, and if that doesn't work, I'm going to have to ask other people to texture my models for me
