Hi there,

I got the same issue. After having the game reinstalled, I lost all of my data. 

I have to start playing from very beginning. Does anyone can help me to restore my data?

Regards,

Hello, Greetings and all that.....  I was forced to update,...upon doing so......ALL MY PROGRESS IS GONE!!!!!!!!! Talk about some BS.  I even spent money on this damn game.

You should all bind your acc when your playing a game dont be lazy cause that will always happen everytime it updates

Go into Google Play and search for Mech Arena: Robot Showdown.  It will then say there is an update.  If you just follow the link from the app and it takes you to Google Play then Google Play may have in its cache that you already have the latest version of the game and just say "play" instead of "update."
