CS5 serial number not valid?

Hello

I change my computer to a Windows 10. Installed PS CS5, use my SN since my last purchase but say PS is not valid! My PS version on my old computer is disabled.

I don't know why my SN is not recognized. I bought PS CS5 directly from Adobe. It was an upgrade to CS3, which was an upgrade from CS2... I also tried old SN, but without result.

No idea how to solve this problem?

Thank you
