I suspect that this might be a domain name issue. You probably logged in over qcad.org but the login cookie is always set for ribbonsoft.com by phpBB. I've fixed the problem by redirecting qcad.org to ribbonsoft.com instead of sharing the contents. Thanks for the report.
Our web site / phpBB 3 installation is only a few weeks old, so there might still be some other hick-ups.
