Since the patch released, getting an exception when logging in to any of my hunters. Here's what I was able to retrieve via BugGrabber:

Thanks!

The stable has been completely redesigned by blizzard. As such, this addon no longer serves a purpose (for retail).

Doh! Yes, just figured that out. Sorry to raise an alarm unnecessarily! I loved the way the addon displayed my pets. The new stable frame is better than it was, but not better than the add-on, IMO. Thanks!
