Extremely annoying notifications about updates

I am so annoyed at this app, and have been so for MONTHS. On ALL of my Macs running Lion, Snow Leopard I get a notification saying "Training for Xcode" needs to be updated, but when I click on it to update I get this weird message about having other apps.

Isnt it about time you FIXED THIS?
