[Quick Fix] If you cannot open the separate quiz & key pdf files...
We have received bug reports that the separate quiz & key files do not open. It seems to be a compatibility issue with Adobe Acrobat (Reader).
Here is a quick fix you can do to bypass this. USE A DIFFERENT APP TO OPEN IT.
(1) Download the quiz/key file in your computer. (2) Right-click the file, and use Google Chrome Browser.
If you are using Mac OS X, Preview app seems to handle the files with no problem.
While you are experiencing the issue, we are fixing the bug at this moment.
