There are some people (mainly those with ATI and Matrox cards) that are having problems running blueprint. This is due to the fact that your OpenGL drivers for the card is not up to date. Don’t worry. It’s not your fault. Hardware vendors are always trying to catch up to the latest technology. Luckily there’s an easy solution:

  1. Go to GLSetup
  2. Download the latest version of the program
  3. Run the file you just downloaded and follow the instructions

GLSetup is a freeware program that will keep you up to date with the latest, full, OpenGL drivers for your video card. Hope that helps (thanks to those who suggested this in the forums).
