misterman you might need to work on your reading comprehension :p
anyway, I'm not sure what you installed already, but lets just assume you only installed greasemonkey. It might be easier just to uninstall and start over.
if you installed the one
here then you probably just need to click onto that top link again and it will finish the process.
If you did not install that one then uninstall the one you installed already, and install the one I linked you to. That one is better in my opinion. Anyway, when you click the link it will take you to a bunch of text. Read it, or scroll to the part where it gives you the url for greasemonkey. go there install that and follow the rest of the instructions given in the text.
