VUDU has quit working

I have a WDTV Live Hub and the VUDU button no longer works, any help is appreciated.

I left out, this is using my remote and clicking on VUDU under services.

So what happens?   Nothing?  Black screen? Error message? 

Nothing happens, it just sits there.

Have you tried a power off reset yet? (Unplug / replug)

Just did that and let it sit unpowered for two minutes, no change.

not working, could be many problems,

you should be more descriptive of what is happening

I think I know what you’re issue may be

I would recommend fix 1, untested

reset to factor defaults

or fix version 2

there is a fix, but requires homebrew firmware and cmd line

both of these options, should delete the file, and allow you to access vudu again
