Hi

We need more information to help diagnose the issue you are having:

• The specification of your computer system including Windows version, see this topic for what is required and please quote processor and graphics card make/model in full, and also what monitor/screen resolution(s)you are working with if this is a laptop.
  
  I would suggest you put this information in your profile signature so we do not have to keep asking for it.
   
• Which Intro did you purchase ?
   
• Are you getting any error messages, if so then please quote them in full or provide screen shots.
   
• Are the graphics card drivers up to date?
   
• A screen shot of the Program settings, Display options tab  would help.
   
• See this tutorial on how to obtain information on the cause of the crash.
