Uninstall fails

For some reason the templates did not install when I installed the product. Now I want to uninstall and reinstall, but...when I try to unintall I get a message that the uninstall failed because there were some files or tables left over and I must uninstall manually. Sure enough, Mobile Joomla is still in the components and in the component list.
Suggestions?
Running Joomla 1.5.15 trying to install Mobile Joomla 0.9.0.

Nevermind...I was installing on a test site and in my haste did not confirm that it was using PHP 5. Made the change and all is well. Now to configure...
