I have exactly the same problem, so annoying! I have tried everything, in three different browsers, uninstalled and reinstalled flash heaps. I can't get into the vanity page either.
Same problem. Could not enter the game at all using Chrome. Was able to log in for one level on Safari, but as I was moving to a new level I got disconnected. Now I can't enter at all on Safari either.
Same thing for me. I played for 15 minutes this morning and can't get on at all. They're probably fixing something today before the weekend so people can get some playing time in.
