Reviewing and writing progress, aka the problem's with Word

Okay, quick update on everything. I've been having a problem where Word (2007) has been freezing up my computer. We've done basically everything possible to fix it, including reinstalling it, and I'm now waiting to upgrade to Windows 10 when I honestly don't want to do before I know more about it.

As it stands, it took me two weeks to write up the review, and I've only gotten a few paragraphs done for this draft of "Project Silver" in the same amount of time. So I'm going crazy, since I just desperately want to write, but it's taking forever because of all of this.
