Hi im also experiencing the same as Jax030310 , I load my gems and press the button and then it freezes loosing the gems ive put in and then I can not even close the window, I have to reboot the game. It did it last night and I thought it was just a glitch but it has done it again tonight (I cleared my Cashe yesterday but it made no difference and it has done it twice tonight the first time it did give me letters when I logged back in but the second time my 7 crystals got eaten but noting back when I rebooted.
I have tried both short letters & normal letters and it freezes both times then when I log back in it takes a long time and the script sequence seems to be out of sinc with text showing from the game before the main information box has cleared, I am getting frustrated as I was enjoying doing the new challenges it was good to have a new set of challenges, so a quick fix would be great please.
