ChristiaanJ, it looks as if the PDF is based on graphics as has been stated before, in that case you will not be able to do anything but use an OCR program. I have done this before with Omnipage and that works quite well but it is not a one-click fix (mind you, there is no one-click solution for this!). If you're still stuck with this next week I could try to find the time to run it through my Omnipage version.
