Default com.android.phone does't work after installing Supremacy script

Hi, i've instaled Supremacy V3 following this post: http://forum.xda-developers.com/show....php?t=1928200. Every thing was ok nad i noticed an improvement in performance of the device, but when i try to make a call the screen turns black and after a while the com.android.phone error appears and i have to close it.
I've uninstalled Supremacy and the problem was solved but i would like tu use it cause it really helped with the device lag problem.
Thank's in advance!.
