Yesterday I tried to save an assembly, in SW 2011, as a step file and I waited for half an hour and still it didn't work. In the Assembly I had two parts that had a lot of pattern features. So I suppressed those pattern features and it worked.
in the layman terms, your parts are to complex and you need to simplify them.
My assembly had only 7 parts. Hope it works.
