Hi there,
I was having the exact problem, and Google searches turned up nothing for me too. I am using Illustrator CS2 and Cinema 4D 9. I have just tried to take Nick’s advice and export as Illustrator Legacy, and save as Illustrator 8… My CS2 does not offer any of these options, either as a ‘save as’ or an ‘export’… What’s the deal here? I really need to find out!
