Now Crashing on loading

Since the update, When I load the app it doesnt let me see my documents, it brings me repeatedly back to the Home screen and wont open.
HOW CAN I REVERT TO THE VERSION BEFORE 5.0?
I need to see my documents and Im about to change App. PLEASE fix this in priority or by Wednesday Sept. 18, 13 you will lose me as a customer.
VERY UNHAPPY!!! :(
