Or, you could try this thing called learning and do what I asked you to do so that we can figure out what you're doing wrong.

I need you type "plugin_print" at the server console and send me the results. If the results suggesyt SourceOP is in fact loaded, I need you to go to the addons\SourceOP\features folder and open up remote.txt. Make sure the number '1' is all that is in there.

Let me know how it goes.
