I think the time has come to upgrade to version 11 (from 10)

But I have a few questions;

first, does the licence cover both charting versions?

second, I currently have Proudman CS3 12km for Europe, is there an upgrade path to CS20, other than paying the full priice of course?

Finally, the Proudman tidal products are said on the site to be valid until 2020, what happens to them after that?
