Cubase AI 5 not getting input from Yamaha mixer

My laptop is running on Windows 8 and I recently installed the Cubase AI 5 software. I have no issues with audio mixing and production. But when I tried connecting my Yamaha MW10C mixer to the laptop, I could not get any input from my connected instruments ( guitar, bass guitar, electric piano). Anyone knows what could possibly be the issues here?
My laptop has a built-in microphone configured as well as having the BeatsAudio speakers.
I do not have any issues using this Yamaha mixer with my desktop PC running Windows 7.

Thank you in advance and best regards,

Will try looking through it once again…
