Hey, wondering if someone could help out?

Downloaded TB 3.9, worked fine.
NOW, however, its not.
Dunno what happened, but now when i go to click a limb it only cycles through extend/contract.
I know that i can use 'x' to cycle between relax and hold, but that is getting annoying due to my finger missing and pressing 'c'.

Thanks in advance

EDIT: i did try reinstalling, but that didnt work
