I get a message that says "A patch error has occurred. Exiting the game. Make sure that your disk has enough space available." and the update doesn't continue.

MIR2M : Grandmaster shuts down with a message that says "Unauthorized access detected."

When I try to download from the Google Play Store, I get a message that says "Your device is not compatible with this version."

What are the minimum requirements for mobile devices and PC?

It says launch MIR2M : The Grandmaster and update at the store, but it won't update at the store.

Constant crashes, freezes, and lags are making MIR2M : The Grandmaster unplayable.

How do I check the OS information?

I can't log into MIR2M : The Grandmaster.
