Open VC : Complex formations bug

[kemalLee61]

I am recently playing the storyline of VC and played a couple of hours, in the beginning I was able to use the complex formations future on my army and also the enter key for distant camera view but now suddenly after couple of hours it dissappeared. So right now the complex formations (f4) doesn't pop up in battles and also the enter key does not work. I uninstalled the mb warband and VC DLC and reinstalled it, load up my savegame and it's still the same. How can I solve this?
