You may need to add more info, buds.

Something like this when you report the error:

This is the error that is produced when the ADD button is pressed.

May have to look at the CallHook that is performed.

Even thought there isn't any image set by myself, and most likely, by zxc7814569, the Kit is supposed to have it's own default image. So, maybe, the image is no longer available????
