Suddendly become impossible to use Translator, every click (change/swap language, cronology, ecc) does nothing

well, it was nice while it lasted. When I first installed it, everything worked like a charm. Then I did a sync with my other computer, and now I can't get it to log into my google account. A window pops up, but then disappears.

Great Idea !! Only if it worked. Youtube videos don't run, gmail keeps loading, google + is empty. Also, a way to login without logging in in the browser itself would be good (So if I run some google app, I can use another account in browser.) Long way to go.

never let me sign in, just kept closing tabs
