I just filled the online form in the support page of http://www.wayfinder.com/

I wrote them telling that I bought a Wayfinder personal 2007 (Europe edition) license for the software shipped with the Nokia N800 navigation kit. I also told them that I found out in this thread that the licenses for that software was supposed to be perpetual and not limited to three years like the one bought for the preinstalled map application shipped with the OS2008 update and I asked them to extend my license expiry date.

I received an answer from support.onboard@wayfinder.com and after an email from them asking some clarification about the version of the software I received another email in which I was told that my license was extended.

Then I updated the license information on my N800 from the menu of wayfinder navigator.

I don't know if now something is changed, you already know they are shutting down their business and I hope for you that is not too late for you to have your license expiry date postponed to 2019.

Good luck and let all us know the results of your effort.
