Using 1550 x 1150 charts and topography will not work. The web site says "You get a FULL, unrestricted 30-day trial to see if it works for you."
So where is it?
While the program (DA Workstation) has be released for sale on the website, it is still not "finalized". There is many features that are currently being worked on, and some features simply do not work at this time. Make sure you download the latest patch, if you plan to use DAWS. Otherwise, I'd recommend using version 2000 until a more stable DAWS is available.
