Exception; Process id error :(

Okay, I am aware not all of this program is running. The text boxes and checkboxes at the bottom are all nonfuntional right now, and it won't print everything if you check all the boxes. When the project runs on a friends machine it generates an error. I've looked this error up in the IDE and it found nothing, along wiht eventid.com, msdn.microsoft.com, and technet.com. I have attached the project files in a .zip document.

The carriage returns are still vbCrLf, because I have not been able to make the \n method which was mentioned to me before work. Perhaps someone could point out to me why the program doesn't work, and maybe suggest how to fix it. Thanks.

I have resolved the issue with the program. I had used the wrong method to close two additional forms. This inturn through a runtime exception. Thanks for your help.
