Mouse Keys No Longer Work

There was just an update when i logged in but then when the game started my mouse keys 1 and 2 are no longer bound to attack and move and I cannot reset them in options. Any suggestions welcome.

thanks

Is the little icon showing the mouse and what mouse to use not there? Strange.

You could try modifying the Ini file, which I believe is Production_Config.ini. It's located in documents/my games/path of exile. The relevant lines, if I'm right, should be the following:
use_bound_skill1=1
use_bound_skill2=4
use_bound_skill3=2

I'm guessing 1 is mouse left, 2 is mouse right, 4 is the mousewheel...
