Delete TotalFinder Mavericks
There is probably a login item that is attempting to run it still in your user account.
In System Preferences select Users & Groups then your account in the left hand list. To the right select Login Items and browse the list. When you find TotalFinder click on the small '-' at the bottom of the list.
This should fix it.
If that doesn't work and the Uninstaller they give you doesn't work then I suspect their uninstaller is running into a permissions problem caused by the upgrade to Mavericks. I would try a reinstall and then uninstall.
