my j key is not working and i use it for move left so its kind of important. It is working in vannila and on FTB.

Check if there isnt any other key on the J.
It might be that there is a mini-map key on it, press M for the mini-map gui and check the keybindings there.

sure ill check ps i have discovered my o key isn't working either.

EDIT nope nothing on either of them...

EDIT2 i reset the keybinds and it was fine??? problem solved!
