Latest adobe update has caused problems again for me being able to access my large amount of files . Adobe opens one minute then it closes so I dont have enough time to read my files . Can anybody help?

I updated my ios10 sofware on Apple I phone 6 plus and thereafter updated adobe app which had approx 70-80gb of pdf books and now I'm not able to open the app at all thus im not able to carry on with what I use adobe for and months of my effort seems to have gone down the drain .im aware this post might not be the one for this problem but can anyone help me .thanks
