DL3 configuration option tabs won't show in CMA

Hey there,

Trying to learn how to use CMA for a DL3. CMA does find the DL3 with the IP number but when I select it none of the six tabs none of the configuration tabs (Server, Fixture, Lamp, Test/Reset,...) show. I called technical support but they were pretty much useless. Anyone know why?

I am on
MAC OSX 10.6.6
MacCMA Version 1.5.3.2043 (that's what it shows under "All Servers")
in "About CMA" it says: Version 1.4.0 (1.5.0.170)
