My Samsung KS8500 Smart TV can no longer connect to Vudu.

Worked fine the last several days, but now says "Error Please try again later" whenever I start the Vudu app. My other devices connect fine.

I went into "My Apps" and told my TV to reinstall Vudu, it downloaded to 100% then said "Unable to install. Please try again later (118)."

I went into my TV settings and reset the entire smart hub, then reinstalled all my non-"basic" apps from scratch. They all worked fine (other than having to re-sign in to all of them) except Vudu, which still won't even start, and still won't reinstall.

I tried deleting the Vudu app, thinking maybe the app has to be deleted before it can be reinstalled. But I was told "Basic apps can not be deleted."

This has been going on for 4 hours now, not the way I wanted to spend my 4th of July.

How can I get Vudu working again on my TV?

Thanks.
