cannot remove an app no uninstall

[apl3]

This may have been covered so I apologize in advance. I cannot seem to remove titanium backup version 3.5.1. It does not show up in my downloaded apps. When I go to manage apps the uninstall button is greyed out but I can remove anyother app. I tried searching for an answer but I am having no luck. Thanks.

Did you remove the key before you looked in your Market downloads? Not sure it make a difference.

Silly question but in what folder are the keys located in. Thanks
