I just bought this from a friend of mine and he says it works on his machine. I am running Motion 3 and the install didnt work for my computer. So I followed the instructions for Motion 2 in the FAQ here and it still wont work. Then, when trying to open the motion projects that come with the suite, they say it is an older motion file and wont open using either choice it gives me. What do I do to get motion 3 to read these files?
