The unlabeled check box needs to be checked before selecting ok on that dialog. If that seems ineffective, I suggest uninstalling the plug-ins and trying again. If that doesn't work, we can continue from there.

So, exact moment: After you have accepted the license, and during the time when it is installing, you will be presented with a dialog asking you if you trust such-and-such certificates. Check off the box next to the first.wpi.edu certificate, and then click ok - you are still able to click ok without checking off the box, but the plug-ins won't actually install. I would recommend "uninstalling: the plug-ins and trying to re-install them, this time specifically checking off the certificate (I'm sure the first time it was just another dialog, don't exactly expect you to remember if you did or not that time).

If this does not work, then please give me a step-by-step of what you did. Also useful would be the configuration details from your eclipse install - available at About Eclipse->Installation Details->Configuration (Under help for me, but I'm running windows, it may be under Eclipse of the far left for you)
