I have the same issue, it takes at least 5 minutes to enter (and several times I am not able to enter) and when I am in the game it takes a couple of minutes for every screen I try to open, it is impossible to do anything, I can't play anymore and I was able to do everything really fast until this morning.

I have also cleaned the cache, updated flash player and so on, but with no results.

I always have the "stuck for all eternity in loading bar" situation!

Please, help us :)
