BIG thunderstorm going on while I did this, so this won't help much, but --- maybe?
The error came-back the next day(Today), after I had(Yesterday) hit "uninstall app"(The Old App "Translator" - green logo), though I think it did uninstall(BOOM!), and I think I hit re-install, said it did - never checked it???
Anyway, a few minutes ago, noticed the same update, with the same error code. With advice from MS site, went to the apps list. I think the old version was still there? BOOM!!!(Cats freaking-out.) Held down the app logo(I think?), got option to "cancel download", clicked that.
Then:
Held down power button until vibrate(Soft reset). Went to store, downloaded "new" app(In pink, called "Bing Translator"), installed same.
Now it's "there", comes-up, tried it - works. Hello is, indeed, "Hola", as I remember...... No sign of old app or update. Will see tomorrow if all stays well.....? I think this sort of stuff is fun, but, can see others who would(Also) freak-out(Which I also think is funny.). Oh well. To each its' own.
