The line that I see on a brief scan of the code that actually adds a new
category to the Categories collection is this:

this.olNS.Categories.Add(Cat.Name, Cat.Color, Cat.ShortcutKey);

Are you sure this line is actually being executed in your code? Maybe add a
Debug.Writeline() call just before that line to verify it is being hit,
otherwise whatever you do won't persist.
