After update: ssets gone, won't hold onto replaced assets

Just like Charmaine, white pages, missing element, frame animations that won't hold the layers.  My app was done, just working on a few games.  I reinstalled the app. then spent the rest of the weekend rebuilding some of the damaged pages. Some things fixed others wouldn't hold the frames.  This morning I open my app ready to take notes to see what is left to fix and get ready to apply some of the new enhancements and I find the app is back to white pages and more missing elements.
   I tried to build a sample page to send you from one of the damaged pages and it created a page worse than the original one I need to fix.  I can't even add elements to replace the ones that are gone.
