Last update broke app

The last update rendered this app useless. After editing a document already in my Dropbox account this app will no longer save the file in the same folder - only the root directory. In addition the file I made was empty (0 kb). I tried editing and saving the file to the iPad instead. Same problem. The new file was empty and all my work gone. At least I still had the original untouched. Pretty much useless now except for reading a file.
