For two days I have "played" the Trivia games but received a graphic saying the site was under repair or some such. Today when I looked at yesterday's quiz, even though I had guessed everything correctly, my "score" was posted at 0%. What gives?
It has to have something to do with your computer or server as everyone else seems to have it working properly. I have been playing there quite often the last couple days catching up with the dates I missed while cruising and have had no problem. Try re-booting maybe?
