NEED HELP!! FINALS WEEK!! PROBLEM!! PLEASE!!

[XXXNoahXXX]

I've been using the trial version of OneNote for law school. It is not finals and I didn't realize, but the trial just expired. So I can't save my notes or edit my outlines!

Is there any way I can either

a) extend my trial

b) buy the product key online for the student version (I know I could get the full one for $100, but I don't want to blow $50. Also, I know I can buy student one for $50 on amazon, but then id have to wait for the mail to come.

Any help???

If it involves less savory methods to access it now so I can get through finals (I'll be buying it for next year anyways, I really love it) then feel free to PM.
