Hmm... Thats odd. Is PDFcreator opening window when you print using its driver?
That shouldn't happen. Close PDFcreator windows before printing. OneNote might
not be able to insert the file because it is "in use" by PDFcreator.

Also try inserting printouts on "current page" in OneNote
(Tools>Options>Send to OneNote)

If this doesn't work, try reseting PDFcreator to its default settings and
starting the tutorial over.

Print to OneNote 2007 - A 64 bit solution

Let me know if you can get it to work.
