I think you will find the error is in menu_1024_768.ini, a refereced item within does not exist, this file may have been moddified and has an internal error or an external part is not there, usually caused by mods overlapping mods. I would recommend any modding be done via jsgme mod enabler and if a mod is going to overwrite a previos mod (put in by jsgme) it will let you know first before enabling it!
