that really sucks about the third button on the mouse thingy. I would say either uninstall/reinstall Maya or you can customize your key and mouse configurations. The middle mouse button is pretty important since that is how you navigate around the viewport. Although it is not needed for the Ocean example...you can simply right click and choose import "oceanshader.ma" into scene or whatever it says. But, I have sent you the maya binary file (mb) to your email. And feel free to plagarize...I honestly did nothing original with it. So have fun working with it. Let me know if you have any questions
