Nathan,
Thank you again for the recommendation to upgrade to Joomla 2.5.28. Unfortunately upgrading to this version did not solve my problem.

I have gone through the "readme_dtregister_J25.txt" notes and followed the recommended steps.
Do you have any other recommendations?
If you do not, would it be possible for you to provide me with access to previous versions of DT Register so I can downgrade?
This could make it possible for me to (a) get things working again and (b) find out which version works and then compare the differences between the version that works and the latest version.
