Our ticket is not being responded to anymore due to the volume of problems.
At this point I want to uninstall everything and delete all the databases...then try reinstalling. We have no active events so it is not an issue from that perspective.
Aside from uninstalling the component, deleting the databases...are there any other files or directories that need to be deleted?
If you delete the database, you will delete the rest of the joomla site, and that could be bad depending on how you use the site. I would think that un-installing dtregister and then dropping the tables would clean it out enough.
