Hi Toby, I've been lucky enough to receive NFR products from you guys for many years and recently received the V3 collection which contains the VDM version. I previously had the CDM but it's licence expired, hence my attempts to run all the kits I've accumulated on that. I've been offered SparkLE at a great price and am just waiting to hear back from Nathalie as to what that can run. Assuming it can use all the kits it's problem over. Thanks for the reply, I understand the logic of making the different version mutually exclusive, makes no sense to invest in creating them if you only need one to run everything eh?
