Urgent: Cannot print multiple pages

I'm an intern and this Thursday I have my assessment, so that's why it is urgent to me.

When I create a multiple paged document in Word I cannot print it anymore to the PDFCreator. 1 Page is not a problem, but multiple pages are.

Is this a setting-issue? Or can it be something else? Last week it was possible to print multiple pages, but now it isn't possible anymore.

Problem is solved. It was a timing-issue in the VB-code.

What was this timing-issue? I think I'm running into the same problem.
