Does Not Work

I have iOS7 and my wife has iOS6. Hers worked fine, but mine locked up, saying "updating app". I closed the app and tried again, but got the same result. I deleted the app & re-downloaded and STILL got the same error. I am not up for trying to troubleshoot- not enough time... Ill try something else...
