Good game, but it something seems to be wrong...

I just started playing this after forgetting about it for a couple of months or so, and it seems to be pretty good. Ive made a lot of progress. However, after I had signed into facebook to get some pearls, I cannot stay on the app for too long until it tells me it is not connected to the server and forces me to exit the game. I dont know if it is my internet connection(even though I have also tried my 3G and it still has the same results), or something entirely different, but if someone can help me through this issue or the game is updated, then I dont believe it deserves a five star rating from me.
