remove the plugin

Hi,
I’m having problem with some of my other plugins since I install the wp-toolbar-removal and I would like to make sure that it’s not caused by it. Is there a way that when I disable the wp-toolbar-removal plugin it put everything back the way it were? I mean, I don’t know if the plugin removes some of the original codes in WP, if so how can I put it the way it were?
