I am new to OneNote and am having some trouble using it. Every time I open the program a dialog box pops up asking for the Product Key. I have tried typing in the key off the CD I used to install my MS Office programs on my new computer, but it does not accept that number (same thing happens to me in MS Word). I have clicked the 'Cancel' button on the Product Key dialog box but then I am unable to type anything or click on any buttons in the program. Also, it seems that a couple of my notebooks of school notes are either gone or have somehow disappeared within the program somewhere. I cannot find them or make them visible. Can anyone help me please? I would appreciate it! Thank you!
