Lady and gentlemen I want to ask you. I have the document in OneNote 2007, but there is a problem, I can't open it cause of - This file does not appear to be a OneNote file. This message has appeared today at opening it. Yesterday the document was valid.

@Is, that tends to almost always install toolbars, adverts and more. I no longer go near that site.
