Crystal Island

My favorite game so far. One or two problems: 1 on my smartphone I cannot play music and Crystal Island at the same time. I have sounds off in CI settings. This is the only game that overrides other apps. 2 I get this error when I try to send to other friends 'invalid access_token' how can I resolve this problem?

Challenging game when it works. Last few days, it steals coins and logs out of FB for no reason, game crashes and reloads without saving progress.

From Quiblix I played Forest rescue 2 and 3 that are fantastik games. Also Candy Riddles that Iam in level 1030 that is wonderful. But this one and others that I had tried from you or are boring or involve money. Its a shame. Had to recapture your creativity to develope more games like mention above.
