Hi We purchased a new IPad about a week ago and have been using it without any issues until yesterday. I had downloaded a book into IBooks and had been reading it every night for the last few nights. Last night I found that IBooks would not open. When I checked, several of the apps that I had purchased like "Numbers", "Pages", "My Radar Pro", "Dropbox", and "CloudOn" also would not open. A couple of free apps that I had downloaded "Calculator Pro" and "RC Plane 2" were opening just fine. Not sure if it is related but night before last I attached the IPad to my laptop (windows) and it synched the I Tunes on my laptop to the I Pad. Since then I have tried powering down with the button on the side, resetting the I Pad by holding the button on the side at the same time holding down the button on the side of the screen until the Apple icon shows up. Nothing has worked. I just tried deleting "My Radar Pro" and downloading it again and that app is now working properly. Only problem is it cost $1.99. I don't want to have to pay for those apps that aren't working. Does anyone have any suggestions? Thanks!
