Please note, using FTP is not a wordpress function. This is a basic skill you should have if you want to play around with websites.
Please read the instructions… if you have further trouble, consult the emails your host sent you when you signed up with them.
if you no longer have those emails, contact your host to have them re-issued.
nobody can help you with specific steps here, as it depends entirely on your host and usernames/passwords you (and only you) should be fully aware of.
Once you’ve connected to your server, simply rename or delete the file(s) belonging to the plugin. If your next question is “what files?” or “what are files?” I suggest you have someone physically close to you help you do this (and teach you about these things).

I’d like to know how you got the plugin up there in the first place, if you can’t use FTP though.
