Need some help with WE

When I try to load up the WE I get to a part where the peons voice says somehthing, then my computer freezes with no error message or anything!

The normal game works all right only the editor doesn't.

And in an editor can you place items?emote_confused

Do you guys think it could be that I only got 128Mb Ram?
Other than the ram I meet the rest of the recommened specs (but damn does it run choppy!)

Any help mega appreciated!
