Got a new motherboard, My Creative Suite thinks it's a new computer. Can't register my serial number, because it can't connect to the internet. Internet works fine. What do I do?

Got a new motherboard after my PC crashed, because my old one was defect. Now my Creative Suite thinks it's a new computer. I can't register my serial number, because it can't connect to the internet, but internet works fine. What do I do? My operating system is windows 7, System is Intel Core i7-4790 / 16 GB RAM
