CANNOT USE W-A-D-S- TO WALK IN CUBE DEMO

Question

Hi guys. I installed wwise a few weeks ago and when I use cube to test if my soundbank work well, it always work. But since one day, when I run Cube and try to walk around to check the footstep sound, I cannot move at all. As instructed, press W-A-D-S keys to walk forward, backward, left and right, but in my PC(I tried 2 PCs), nothing happened. What I can do is to throw the IceGem and Jump with Space, but other keys won't work. I have tried to reinstall the software but the issue is still there.

Is there anyone who have run into this and maybe can provide a workaround? Thanks
