Configureable USB Loader

I am using Configurable USB Loader (not sure what version, says v51 at bottom corner). Wii has 4.2U on it and wireless internet connection. A couple of days ago the USB loader stop putting on the images. Does one of two things.

A. "Networking Error.." Then freezes.
or
B. Stack Dump and then I have to unplug it.

It stopped just a couple days ago about getting the images, how do I fix this or find out what is happening?

Oh yeah using the latest WBFS.

I suggest updating to v59.

i ended up getting it to work this morning, when my router firmware updated it renamed the ssid, so it wasnt connecting then i updated after that
