Thank you, I will use CC 2015
Where can I download CC 2015?

You won’t be able to get an old Illustrator from Adobe legally. It might also be difficult to install such an old version, even if you have a serial number.

oh no, how can I use my fontself?

You need Adobe CC. This is currently only available as a subscription, see https://www.adobe.com/products/illustrator.html.
