I have an evo shift which runs the andriod 2.2 OS. I downloaded the authenticator from the market place and installed it with no issues.
When i went to add the authenticator to my account it said that the serial number was invalid ( i navigated to setup first and entered the code with -'s in it) I clicked the blue "get new key" button at the bottom and received the error "There was a problem generating your serial". I tried this a few times and then uninstalled the app and reinstalled it. Now when i launch the application and go to setup i receive this error every time.
