Unable to get hold of unlock codes for Game...

Poked around a bit and it apparently is Mcmillian software. Can't really suggest anything of substance but there are some forums on the net. Suggest you poke around...the folks that use this software are probably a little into the geek world and might know of something. Cracks in general are jokes meaning often filled with viruses, don't work, weren't intended to work, etc. You'd have to go thru a hundred or a thousand (even if the name said crack for xyz) to find something that would work. Your time, your life...Tango.
