Not without further info... Which version of OpenCPN
are you running? Are you sure you downloaded plugins that are supposed to work with it? Where did you put the plugins? What do you mean by doesn't work at all? - grib plugin is bundled with opencpn
, so there should be no problem even if you made a mistake with the plugins you downloaded separately. Can I see your logfile? (Click on the ? icon in the toolbar to find it's location) - the part from the last run is enough, no need to post the whole file which sometimes is big and no need to answer most of the previous questions as the info will be in there.
