Your blocks are probably too big, or your buildings are made of too many and complicated blocks.

Try following one of the many level building tutorials available.

Besides that, make a quick screenshot of your WED-Interface,
that shows you buildings, maybe we can see something that will help you.
And how fast is your processor?
