clean everything up and look at the threads real good. unless you really forced this chances are good everything is OK. However if you live near a bikeshop it never hurts to have them chase the threads for you.
you do use the old trick of holding the cup up to the BB and turning it backwards until you hear/feel the tick from the ends of both threads. then start slowly turning the correct way. always seemed to work for me.
