Ryan,
I tried your exact code. It doesnt display the message groups either. Areas work fine. Does your bt-gasel work? Are you running A46?
Yeah, I think I have some custom configs or something.
See if you can figure out the difference between my mpl and the original,
there are some new group configs and you'll have to refer to the pascal data structures included in the upgrade to understand what needs to be changed. Sorry, I rebuilt mine a while ago, when upgrading and it initially broke for me, and can't remember what I did :)
