Hi there, this error code usually means the device you are using has been rooted. If your iPAd is routted you will need to factory reset as we don't allow rooted devices.
If, however, your iPad isn't rooted, please try deleting the app and then re-installing it. The steps is the same for Android devices as well.
In regrads to the 'contact us' option, please see HERE for instructions.
I hope that helps.
