When you play Era on a computer do you see a black screen?
If you have experienced this "black screen" while playing Era on Facebook or on Era.Graalonline.com don't worry you are not being hacked. I don't really know why the problem seems to be and what caused it ,but admins are looking towards this and trying to fix it. I even have the black screen myself really. So if you are seeing this black screen on a computer go to a mobile device and play it there. If you have any questions reply to my thread below and I'll try to answe-r.
