I downloaded free app for word to my iPad. I started composing a rather in depth historical document which I worked on for 4-5 days. Each time I opened word the document appeared. No problem. I never did name the document but word was saving it constantly. Today I tried to use app but it was frozen. I reset iPad, still no document and word still frozen. I installed upgrade to my ipad 8.1.2 I think. After download complete word is working perfectly but the document is not there. The thought of re-researching all this material is painful. Help!
