Default Xposed Installer problem/issue

I have root acces, busybox installed and custom kernel with stock jellybean on my HOX+. I have installed Xposed Installer 2.4.1 and i have tried install/update framework button but app freezes and closes after some time. I can't install framework so I can't install any modules. What should I do?
EDIT: I have tried many times and after some time supersu popup showed and sked me to grant acces and then it worked but when I try to reboot from Xposed Installer it says that I don't have Access to do that.
