The machine hung up on me after i entered the numbers. Why does microsoft hate me. I know it's so stereotypical to bash microsoft, but I get so angry at these over-looked usability issues. I've dumped 45min into this already and am so frusterated. Anyone experience this, with office 2011. What number did you call?
