I'm looking after a 1 day event - so I've got about 5 hours from first laying my hands on a hired Pearl Tiger until show time

So I'm trying to get familiar using the SImulator and Visualiser.
I've managed to download new personalities into the visualiser, but I can't seem to load new personalities into the Simulator.
I've got a small show with 4xMAC250 and 16 Stairville LED Cans. But I can't seem to patch these on the Simulator (as it does not seem to know about these personalities).
Any pointers greatly welcomed.
