pack

I've downloaded some GT3 skins and now I wanted to put them all together as a mod package so I dont have to select every GT3 car for Ai after I changed my car. Somehow I get this error. Can anyone help ?

In a championship online we need to disable upgrades (BMW: no Low Drag) and set the simultaneous stop & go to the pit, but the command "StopGoSimultaneous=0" is in physic.hdv, cripted file, and is not editable. How can we solve the issues? Thanks
