Help please - Killswitsh is blocking CIS.exe

I somehow managed to kill and block one of two CIS.exe processes with killswitch. The other is running, CIS window is starting at startup, but when i click anything on it, it tells it cannot load due to problem. The result is that I cannot uninstall/reinstall CIS, nor run any of CIS functions, and even i cant unblock this process in HIPS settings.
Is there a way to unblock it? Idealy through Killswitch which works still well? Thanks

What process of CIS is getting blocked?

I assume you cannot open the user interface to remove the block rule in HIPS settings. Try booting into Safe Mode and then open CIS.
