Netbook keyboard and touchpad stopped working

Hi

My netbook is a Samsung n145plus and has 8.1 installed with all updates. (even if it's not officially supported but it works amazingly fine)

I've installed the officia Samsung Elan touchpad driver as it seemed to work fine (it's for Win 7) except when scrolling with the edge of the pad because a Elan window appears on the taskbar and was annoying so I installed a newer driver but for a gateway laptop it installed fine but it wasn't detected by Elan in control panel so I removed it.

Now both the keyboard and touchpad stopped working and Windows says code 19 for keyboard and code 10 for touchpad. A USB mouse works fine. I've reinstalled both with Device Manager without success. Now the netbook is almost useless
Thanks

Reinstalled twice the Elan driver and now both it and keyboard work I don't know what does the KB have to do with the touchpad...
Now I will try to fix the aforementioned bug when edge scrolling

Whenever I uninstall Elantech touchpad driver the problem comes back plz can anyone help? The program is very buggy on 8.1 and now I have to keep it installed to make the INTEGRATED KEYBOARD and TOUCHPAD work how is this possible? before that is was fine with generic driver and Device Manager can't fix. Hope I don't have to reinstall windows
