App crushed

[gaialestrange]

Every time since this morning I have tried to open the application it tells me that I have to update it, but on the App Store the application has disappeared.  I am writing from Italy, I do not know if it is a problem with the new update, but in my country the app store tells me that the application is no longer available, I have been playing this application for years and I have always liked it a lot, I want it back available
