Jon,

Silva Elm is still present and thanks for raising the issue that the Buy Now / Renew links have been inadvertently broken - I am currently trying to resolve this problem with the Online Payment provider.

Regarding the issues you have raised previously (circa 2015), the next version of Sense will not need Registration / Product Keys - simply the License Key that is provided at the time of purchase.

This does mean that there will be no license expiry with the ability to re-install using the original License Key on a different machine.

I do hope this helps and alleviates your concerns.

I am planning a new release of Sense later this year following a rather extended development. more details will be released in due course.

Regards

Dave Ewins
