Pew Pew weapons wont shoot

Does anyone have any idea what is wrong? I downloaded it with Tortoise SVN. I can spawn the weapons that are used in Pew Pew but they never fire. It is also located in my addons folder. I have tried reinstalling it several times but it never works, this leads me to believe that I am not installing it properly. Could someone please tell me how to properly install it?

EDIT: Yes, I have attempted to fire them with wiremod, it does nothing. I have also made sure that the weapons are allowed to fire with the admin tool.
