yea after i bought it and in the last page of the manual is where it says it's not cross platform. simply doesn't work. used the rendercow that came with the windows version of the vue demo and it refused to update that machine and go. i think they should have made it more clear - even this forum tought it would probably work with just mover 5. now i wish they would just say give me x amount of money and your mover will do what it wants. i look at that upgrade list and get a headache trying to figure out what to do. thanks
