Shit! Yeah - I got it, but I wasn't feeling well yesterday so I spent most of the day on the couch
I can't duplicate the problem that you're getting, because it just times out for me
The timing out problem is an issue that NatNet is working on, but pretty much coming up with blanks
I do have to call them later today anyway, so I'll be checking up on it to see if anything is new on their end.
