@linseyja - I'm sorry to hear that. Did you use the "Fix Posts" and "Fix Pages" feature documented in the readme to correct your pages and posts? Did you create a backup of the site, which is recommended, before installing the plugin?
If you have completely uninstalled my plugin and you did not use the "Fix Pages" and "Fix Posts" admin utility then there is nothing that my plugin could have done to affect your site or other plugins.
I can certainly be of help to you, but exclaimatory remarks like "Thanks for nothing!!!" are not the nicest way to ask for it. If you would like some help, can you please answer the above questions and post the names and download links for the other plugin(s) still not working for you?
This plugin has a great track record for solving some long standing issues with the editor in WordPress. I don't take offense to you ranking it 1 star, but there are thousands of other users who are quite happy with it. And for the very few who have had problems I've consistently helped them to resolve their issues as seen in the other support threads for this plugin.
Thanks in advance for your patience, I hope to hear back from you.
