Your 7 day certificate has expired. Please reinstall ++ via impactor. If you want to keep all of your ++ settings, do not delete the app, you just need to impact over the existing ++.
Reinstalling IPA after seven days:
In order to reinstall after days are up (crash at start of game), you will need to revoke before you click and drag IPA:
- Open impactor
- From menu select XCode and choose Revoke Certificates and enter same apple info you entered when you impacted prior and press OK when prompted
For Mac users if you are unable to see menu, look at the top left corner of your screen for impactor menu and follow same steps.
