Update the version of your plug-in using the internal plug-in manager of
OpenCPN at Options|Plug-ins. Update catalog and look for plug-ins marked for updates.
A "refresh chart list" at Options|Charts|oeSENC will list your licensed chart sets and their actual status.
The licenses of the charts are valid for one year. During this time frame you can request charts (always the latest actual version).
After that time it is not possible any more to request sets.
If you have the set still on your
phone or tablet, there is no reason that it shall not be displayed. Is there any error message?
