When running /install/default.aspx - I have to delete yaf_PMessageView, yaf_vaccessfull and yaf_vaccess to complete the installation. A second visit to install/default.aspx renders no errors.

However, any operation on the upgraded forum to create a post, user, forum, or change a setting - cause a "Cannot insert the value NULL into column ..." fault.

A clean install on an empty DB works.
