Joomla: 1.5.26
CB 1.9

I had a site functioning fine up to yesterday when I went in to approve a new subscriber in CB User Management. I can see and sort all the users but when I try to alter a user like delete or approve I get a white screen like it's going to work as you'd expect but it never gets beyond that. I updated Joomla to 1.5.6 from 1.5.5 and then downloaded CB 1.9 and updated mod_cblogin.zip, mod_comprofilerOnline.zipmod_comprofiler, and Moderator.zip. They updated fine, but com_comprofiler.zip, which is what I need to update to fix my problem won't upload.
anyone have any ideas?
