@PPLepew: Have you made sure you have the Florida region installed?
NOAA is in the process of “re-scheming” all of their vector charts (see Rescheming and Improving Electronic Navigational Charts for more info). Part of this means that the identification of and areas covered by every single chart is changing. And that means that some areas for which you’ve had up-to-date charts might not be kept up-to-date anymore if you’ve only had individual charts installed since those charts may no longer exist.
However, if you use the option in Coastal Explorer to install complete regions of charts, then any new charts that NOAA adds to that region will automatically get installed by Coastal Explorer (and charts that NOAA removes will be hidden).
To install a complete region, use “Settings > Charts and Add-Ons > Store > NOAA > NOAA ENC Vector Charts” and click Install on each region you want from that page.
