Word 2007 compatibility pack

You get a story with this request:

I'm in high school and I had to take a practice interview. I made the resume on word 2007.
Before you start flaming me about using M$ or software that cost money, please understand that I need office, because I need it for my business class, and Open Office 2 sucks. :shrug:
So I made this word document and I was too stupid to realize that the school still has word 2003. If you don't know 2003 and 2007 word save their documents in a different file format. I saved a .docx (2007 version) file on my flash drive to print at school. When I got to school and plugged the drive in, it was chicken scratch. I looked for a compatibility pack and I found this:

Unfortunately the school network at my school can't download files that are 25 mbs or bigger. So I spent 2 hours working on a resume and cover letter and I can't even print it out.

I would love you guys if you could make this portable.
