Remove configuration/settings data of Easy Blogging?

I had to remove the Easy Blogging plugin via FTP (deleted Easy Blogging folder), because I locked myself in Easy Mode by accident.

When I re-install the plugin (via WPMU Dev Dashboard), my configuration remains the same and I am locked out of normal wp-admin, so I had to uninstall via FTP again.

How do I remove the configuration/settings of the Easy Blogging plugin?

This would allow me to finally set-up this perfect plugin correctly, so I can set it up again and use it (without blocking myself from the normal wp-admin dashboard).
