Missing css stylesheet and archive already mounted

  1. When I tried to install Newspaper I got the “…missing css stylesheet. Install failed” message.
  2. I tried to post a question on the forums but it did not post.
  3. Then I tried to install again and it said “Archive already mounted.”
  4. My themeforest purchase code is: [Removed]
    Thanks in advance for your help,
