GoodReader PDF Editor & Viewer funktioniert nicht

It's like bringing your personal computer experience to your mobile device — easily managing huge collections of files and folders will make you forget you don't have your laptop around.  Adding notes and drawings, highlighting text, and then sharing your annotated files or annotation summaries will be your main productivity and collaboration asset.  This wonderful feature allows you to split (*) an iPad screen in half, to read two files side-by-side.  While reading files is a big part of GoodReader, it's not all it can do.  This is what you can view in GoodReader, plus you can also annotate PDF files and edit TXT files.  It can also serve as a central hub for all your files, even those that can't be opened by GoodReader itself.  And it's completely independent from the built-in Apple's Data Protection, so even if a hacker steals and unlocks your device, your data will still be protected by another strong layer of security, our own.  Download, upload, and sync (*) individual files or huge folder collections.  PDF files is where GoodReader truly shines.  With GoodReader, your data security steps up to the level previously only dreamt of.  Dropbox, OneDrive, Google Drive, Box. com, WebDAV, SMB, AFP, FTP, SFTP — these are all accessible from inside GoodReader.  With Pro Pack® (*), our new set of professional-level super-features, you'll get AES-256, a military-grade encryption, for all your data, at a price of a cup of coffee!  You'll be surprised how much better PDF reading goes when you don't have to scroll left/right all the time, for every single line of text.  GoodReader is a perfect combination of document-reading and file-managing capabilities.  We're proud to say that after 13 years and counting, we've been delivering wonderful updates with extraordinary new features.  PDF, TXT, MS Office, iWork, HTML, pictures, music & audio-books, videos.
