So after many weeks of trying to get an offical response from anyone at Altium, or Farnell Avnet (aka E14) it would appear that CircuitStuidio is dead.
Please do not buy any more licences people - it's dead. As in, no more updates, no more bugfixes.
Looks to me like CircuitStudio was a failed experiment, and E14 / Altium are too scared to admit it.
They should at least do the decent thing and stop selling licences and maintenance fees for it.
BTW: RIP = Return if possible.
