Hi, I just bought today (Sunday Dec. 1, if that has anything to do) the Microsoft Office Professional Plus 2013. However, upon attempting to activate it, the 25-character comes up as invalid. How can this be solved?
My receipt shows the order date as Monday Dec. 2, I wonder if that is relevant to this issue. Thanks in advance Microsoft staff for helping this not-geek soul in a prompt manner, because I must avoid further work delay and start using my new computer with the software asap.
