I installed the engine ok with the serial number but cannot work out how to use the number to register and unlock the program. It has a 'Your name' field, a 'Serial Number' field and a 'License Key' field. I only have one number but it seems to be too long and won't fit anywhere.
I received a prompt email explaining that there were two products, the engine and the program. I'm putting my confusion down to snow blindness from that brighter than bright hiarcs website.
