@nsnbc: As I stated to you before, you will need to use FTP or SSH to access the files on your website itself in order to remove a malfunctioning plugin.
If you do not have any ability to access the files on your website directly, well, then you're kinda stuck. I mean, the bottom line is that it's your site. You need to be able to manipulate the files on that site.
WordPress is just software that runs on the top layer of the site. It's a publishing tool, not a file management system. It just gives you a way to easily publish content, it doesn't actually have total control over the site itself.
If you don't know how to access the files on your site, and you don't know what FTP and SSH mean, then I suggest you contact your web hosting service and ask them for support.
We do have some information about FTP and such in the codex, but really, this is super-basic first-step kind of stuff. You cannot create a website without manipulating files on the site.
