[LE] CK won't render cells properly

[ISOWarrior]

I've been trying to position an NPC in a cell using CK, but when I try to load the interior cell, it renders it like this.

 

Also, my CK just doesn't render the full view of the NPC in question. The only thing it renders more or less successfully is the head.
I haven't installed any graphics mods since the last time I ran CK, so I don't know myself what causes it. Any ideas why is my CK acting up like this?
