Two finger scroll doesn't work in Acrobat Reader in Windows 7 bootcamp

It works only up-down, and the opposite way then in other apps (You need to move your fingers up to scroll down). It doesn't work left-right.

This is a problem when I read newspapers, text is too small to read if I put it all on the screen.

 

But bootcamp is loaded, and works elsewhere. Acrobat Reader is not using windows drivers imo (because 2 finger swipe works up-down), but is messing something up.
