They can do what they want.
All I am saying is myDMX's direct and popular competitor - SHOWEXPRESS is much older and releases an upgrade/update every few months and can play multiple scenes.
MyDMX has multiple universes -- something of higher systems, and in my opinion, totally unnecessary on an "entry level" system.
Another program that I used to use - Omnirush (a CRM add in) decided it didn't want to bother being Vista compatible. We have paid maintenance costs and they still won't. We are stopping use and I bet that company will go out of business soon.
My guess is that AMDJ is phasing out it's myDMX for something new.
