Have installed Office 2013 Trial and have license key but now stuck

[zlloyd1]

I downloaded and installed the Office 2013 Pro trial last week, and this week I got the license key to completely activate it, but I am not sure how to proceed now as it still says I have 52 days left....
How do I use this key to fully activate the software please, and thanks in advance!!

no option to activate under "File - Account"?

From Microsoft when I purchased it, but I have it working now though....
Thanks for responding nonetheless!!
