Got a prompt saying I had Word until November when I booted up offline. Now it asks me to pay.

[Safe-keeper]

So I just bought a new laptop, and when I started it, without access to WiFi, and launched Word for the first time, it gave me a couple windows about registration/Internet connection -- one of them saying something like "let's try this again" (I'm using a Norwegian-localised version of Office), and after hitting some buttons I swear I got a message about how I had access to Word/Office until November this year.

Problem is, when I next booted up the laptop, this time with Internet connection, Office apparently had forgotten this and now wants me to give it my email address, and then asks me to buy Office to get it out of read-only mode.

Did I just somehow badly misread/misremember what the prompt told me, or is there a way to fix this? If Office comes with my laptop, I don't feel too inclined to spend about $100 on it . Any help?
