- If you have USB Loader GX installed as a channel instead of as a forwarder (you installed the WAD file instead of the DOL) then you'll get a black screen and it will return to the Wii Menu. The Netflix forwarder only works when USB Loader GX is installed as a DOL on the SD card.
In my case, I have the WAD installed. Was able to get Netflix working by putting the DOL file onto the SD card. Basically, I am running both versions (DOL and WAD) of the loader. Make sure if you do this that you use the SAME version in both places. They use all the same config files, and running different versions will probably mess things us.
The only other option would be to remove the USB Loader GX channel altogether and use the forwarder instead.
- If you get a network error when launching this the first time then go back to the Wii menu and access the network using a different channel (e.g. Weather or News). Once you have successfully done that then relaunch Netflix. Should work. Note I only had to do this once. After that it just always has worked.
If that doesn't work, go into settings and delete all your network settings. Reapply the settings and you should have the network back.
