If the cups aren't threading in all the way, that's your problem. Ideally, a well-equipped shop or home mechanic would chase the threads and face the ends of the BB after a paint job. See if you can clean the threads inside the BB with a very stiff wire brush and clean all the paint off the faces with a file.
