My update policy
My policy is to provide updates to existing customers at a nominal price to cover my time, and the cost of postage and packaging. That cost is currently $25. I will also require the old disk back as proof of original purchase.
What updates are available?
From time to time, I do make updates to the maps. These can be either data updates, which have updated data, or design updates, where I have changed the way the map displays. This may be fixes to errors that that I have found, addition of more data, or changing the way things are arranged.
As of the release of version 4, I will notify new releases in the forum. If you register on the forum, and subscribe to the Versions topic, I will notify new updates in there.
