Did the 50 cent 3-year-upgrade, now have to pay already?

Good evening,

On 28 November 2012 I bought TomTom West Europa for Android.
Then on 23 June 2015 I did the 50 cent 3-year-upgrade to TomTom Go Mobile, allowing me to continue the use of TomTom for 3 years.
But now since a few days after I downloaded the latest maps, a message on the screen appears saying "Gratis km: 68 [Upgrade]" meaning I have to pay for navigating after 68km. I expected this message after June 2018, but not already now.

What is going wrong? I am going on holiday abroad on Sunday so I am in quite a hurry, would appreciate any advice on this.
