Your mod is likely out of date. You can either go with that and remod your system with our Softmod Any Wii Guide, or you can post a syscheck and have us confirm this before doing so.
Both guides for modding and generating and posting a syscheck are linked in my signature.
Also, if you are referring to CFG USB Loader v70, that is definately out of date.
I have the current version v70r51 linked in my sig as well, or if you go through the Softmod guide, install the app pack in chapter 3 and it will give you updated USB loaders and additional apps.
