I installed iFolder for OSX, and it was working fine with the server.
I renamed the default ifolder in my OSX, and it didn't work anymore.
I uninstalled iFolder and remove the ifolders.

Then I reinstalled iFolder.
However, when I start iFolder, it doesn't ask me to set-up a new account, and the Preferences panel is disabled. I cannot set-up anything.

How can I completely uninstall iFolder and reinstall it from scratch?
