Thanks everybody. I read the new log file and as I did not find apparent oecservrd errors I restarted Opencpn & tried to load
charts... Surprise: my sysstem now produces the .fpr file. No idea what happened before or why. I am at your disposal if you wish to find the reasons of
malfunction. In the meanwhile, thanks Dave and Hubert for the great assistance.
Ps: I still do not manage to get the
charts directly via the
plugin in Opencpn (I had to request a download link to the shop) as, strange enough, even if I authorized the new system with the new .fpr and I selected the charts with the
plugin, no "download" button appears. (see attachment).
