I live by the khanacademy. My school's curriculum is pitiful at best. So, I downloaded the khanacademy app, and downloaded all the videos I was interested in so I could see them offline if I brought my ipad to school. Unfortunately, after three months of flawless performance, the app doesn't start anymore. If I had only donwloaded 512 MB or at most 1 GB I would just reinstall the app... but I have 10 GB which I have no intention of redownloading, and I'm fairly sure reinstalling the app will make all of them magically disappear. So, can anyone help we with the following? A) Fix the app without losing those 10 GB, or B) Access the downloaded videos from the videos app that comes with ios, or C) Be creative! Suggest your own solutions, because I don't know much about apple devices. I DO have access to a mac, but my laptop only has linux and windoze. Thanks in advance for any help. Also, since this is my first post, can someone let me know how to mark the thread as solved?
