Hello,
I bought Istopmotion 2 (in a box) because i have a mac osx 10.5 and istopmotion 3 doesn’t run on my computer.
I recieved an email with my activation key,name and product but the activation works only with istopmotion 3.
How can i do to use istopmotion 2 (because i bought it and i don’t want to pay for osx snow leopard 
)
thank you for the answer
