I Can Hear the Course Audio, But I Can’t See the Instructor Video

Introduction
This error has been seen when running one of our CD-ROM courses listed as a “KeyStone2” type. To see if your course is on the “KeyStone2” list, please click here.

The following issues are typically fixed with the updated KLSUCDROM.EXE file:

  • When I launch the KeyStone course, I see a small black screen, but nothing happens.
  • I see video player controls, but no video, and the controls do not work.
  • The first (typically the instructor) video of a topic plays, but nothing happens after that; the next video does not play and/or I am not returned to the menu.
  • I get a dialog box with the following “Critical Error” message: “An error occurred when attempting to open the database connection: Method ‘‘ of object ‘‘ failed”
  • I get a dialog box with the following message: “…Windows has blocked this software because it can’t verify the publisher”
