Windows 7 touch pad edge scroll ELAN not working

Hello,

So, suddenly, the edge scrolling on my W7 touch pad stopped working.
I've tried different solutions, such as disabling other options (two-finger scrolling), making sure it's enabled, etc. But nope, still nothing.

I've got no idea what happened. Just at one moment when I tried to use the touch pad scrolling again, it didn't work.

Any potential solutions that could work?
