Hi mismas,
if you paid $5000 or more plus annual subscriptions as is common with pro software
you can expect/ demand support.
Mach3=$175, no subscription.
If there were say 20000 licenced users, total 3.5 million over Mach3's entire history, over ten years!
I don't imagine there'd be anything left over for support.
The community of users ie the forum is the support and that's voluntary. I realise it can't address
licencing issues but it is what it is.
The commercial version of Mach4 does have phone support but it costs more.
