Greetings. I have 3DS Max as a free student version. I installed the software in a computer, but I sold a while a go. (I uninstalled from that PC). So I had to install again in another PC. But the software does not accept my student license and gives me just the 30 trial days. Can anyone help me? What Can I do? I have the software for 4 months, and is suppose to be for 3 years! Thank you.
