Q: app called monster busters will not open up in my iPad  air

It sounds like your saved game is cached in the cloud somehow (possibly by signing into Facebook?).

I would recommend uninstalling and reinstalling the app.

Your game is crashing. Monster Busters was udated on May 11th and the update may be the cause of the problem. I'd check with Monster Busters first.

I hate contradicting my fellow contributors (sorry TMHahn) Deleting and reinstalling is usually the correct course of action for an app that cashes but with a game you'll probably lose all your progress if you delete it.

No apologies necessary, bobseufert! If I'm wrong, I'm wrong. This gives me a chance to learn, too. I was having problems with "Words with Friends" crashing on my iPad, and knowing it was available on the web and my iPhone, I discovered my game was saved in the cloud. I thought the same thing might apply here. Deleting and reinstalling fixed my problem.

Thank you. Some people seem to reveal in finding fault, I can barely disagree. It wasn't that long ago I was starting out in ASC and some people would politely point out my error and some would be jerks. I count that first group as my longest friends in ASC.

Games can be tricky with the deleting and re-installing. Some games go out of theit way to make a save you can re-install. Some games let you know if it's deleted all progress is gone. I always lean to the better safe then sorry. If somethings wrong, first a reset. Then if the game is still having trouble contact the developer. Updates in both the game and IOS can play havoc with games.

Did you tell it was only on following their advice did you lose your game progress ? Also see if they have a active support Forum. If nobody posted in months don't bother.

No forum... Contact is their "Help Center" > Can't even make contact without a customer number > http://www.purplekiwii.com/mb_contact.php

Thanks for the help and clarification.

Any chance you made a iCloud or iTunes backup before losing your game progress?. If yes the article below is a good place to start.

You said you were "temporarily" locked out of Facebook - were you able to log back in?

If so, you need to make sure you re-log into Facebook inside the game again, too. Your saved game might still be available through Facebook!
