acer e5 511 multitouch not working after bio update

So I've decided to update my BIOS on my laptop Acer E5 511 and afer that my touchpad lost the abilitiy to work on mutlitouch gestures. 

I can't scroll ,zoom or do the right click by presing with two fingers at the same time.

I've tried isntaling the touchpad drivers from the official site, restarted my laptop a few times after but nothing helps.

If anyone had the same problem and found the solution please share, I've gotten to used to the multitouch features that now I feel diseabled everytime I use the touchpad just for movin the cousor.
