SEAiq users in the USA downloading the US Army Corps of Engineers charts for US rivers may have noticed many of the charts were lost in recent update. This is caused by a change in the format of their chart catalog. The US ACoE have been alerted and we are hoping for an updated chart catalog very soon. We will post updates here as we find out more.
In the mean time, users with an immediate need for these charts can download and install the USACoE charts manually here:
SEAiq Pilot users can turn off "Automatic Chart Downloader" and then follow the instructions in the Help on the Charts tab to download and install these charts. SEAiq USA/Free users can download SEAiq Open and load the charts. SEAiq Open includes a 1 week free evaluation, by which time this will hopefully have been resolved.
