I received a letter today that contains important information and every time I try to open it the game just freezes. I have cleared my cache/cookies/browsing history; Logged out and back but I still cannot read that message. When I click on it, it opens but displays nothing and then the game is nonresponsive.

I have never seen such a thing but if it was sent to you from someone, request they resend it. If you did all the appropriate things and nothing seems to work, my best suggestion is to submit a ticket to support at https://plariumsupport.zendesk.com/hc/en-us/requests/new
