Access problem [Solved]

Greetings from Norway :) Hello, I've bought the book "Beginning game programming 2nd edit." by Jonathan S. Harbour and I'm now on chapter 10. (If anyone has read the book ;)) But I've got an access problem. I get this error message when running the program (It does compile without any errors)

Had same problem when started to use DirectAudio, so I used the framework from the CD in this chapter cause I thought it might work better. If you need more info, please tell ;) Image of the program after compiling: http://img267.imageshack.us/my.php?image=20070618002505rj8.png [Edited by - NorskFirefox on June 18, 2007 5:42:21 AM]
