Windows 7 Not Genuine (Replaced Motherboard)

I have a K43SJ Asus Laptop and orginally, it has a Windows 7 Home Premium pre-installed in it. I installed Windows 8 (Genuine)some time last year. My motherboard broke down three months ago and it had to be replaced by a legit ASUS repair center. Now, I have decided to go back to the original OS because I do not want Windows 8.1 anymore. So I reformat it with the OS inside the hidden partition of my laptop. Then after installation, it says that my OS is not genuine. How can I fix this? I'm pretty sure this is genuine. BTW, here's a copy of the MGAdiag.exe report
