Regular WP Comments not working Properly after Comments+ Removed

I installed Comments+ but I could not get it to function properly with my current setup. I deleted the plugin from my server but my comments section is not acting properly.

It will only let uses who are logged in post comments. I have set that to be OFF in my Discussion settings but it still shows comments are close on my blog page.

What tables does Comments+ create on my db – I would like to DROP them as well.

Please let me know if you can help me solve this issue.
