When you installed the plug-ins, did it ask you to accept a certificate? In that certificate accept pane, did you check off the first.wpi.edu certificate and then hit OK, or just hit OK? Eclipse has a strange property of allowing you to continue without accepting certs, and then just not installing anything with that cert - without telling you. If you go to the install new software page, on the FIRST update site, and they are still available for download (including being colored in to indicate they are still not installed) then this is the most likely issue.

Otherwise, please give me some more details about you eclipse install.

Also, note that once the plug-ins are installed (or before), they will need Eclipse to be setup to use the Java Development Kit (JDK) instead of the Java Runtime Environment (JRE) - instructions on how to do this are in the help contents, which will appear once installation succeeds.

I can't really think of any other reason for the install to silently fail - if you are getting an error dialog at any point, please tell what it says.
