1. I am on the DIN and cannot open PDF files.
Right click on the link with your mouse, and click "save as." Then you should be able to open the file.
2. The page I am trying to access won't open.
Maybe the link is broken. Please report the problem and we'll fix it.
3. The page I am trying to access takes too long to upload.
Some files contain whole documents and are quite big to be upload through the DIN. However, it still should work. Try it on a standalone computer to see if it really works, and please report the problem if it still does not.
