I have arena installed on my tablet and for the past 2 days (10/22 & 10/23) I cannot get it to work. I lost track of the number of times I've uninstalled and reinstalled the app. First it will give me some error ("Error Updating Data: Please check your connection and try again.") trying to the load the loading screen and I have keep tapping "retry". And many attempts it finally asks me to download the updates (almost 3 GB). Once it's done downloading I have to sign in, but I get an error ("A unexpected problem occurred (Error code: -1). Please try again.") when I try, and I most definitely have the correct email and password.
