Issue with GE Link Bulbs after Disconnecting the Hub

I took my hub home over Spring Break to mess around with the Arduino Shield I got for it. Upon returning and plugging the hub back in, only a handful of bulbs can be controlled by the hub and they don’t dim anymore. Any ideas as to what I could try? I have 15 bulbs, so if I can avoid removing and reprograming all of them I would prefer that. Thanks!
