I've been using my oeSENC charts
on my RPi now for a few months and have not had any difficulties, Since installing them I've updated them from version 2017-1 to 2017-8. I'm really pleased with them so thank you to all involved.
However I'd now appreciate some clarification please. I've been using OpenCPN
v 4.6.x as part of OpenPlotter versions 0.10.x to 0.13.x and throughout those updates again I have never had a problem with the oeSENC chart licence. But I find that the development versions of OpenPlotter seem to induce a bad performance problem (not surprising, it's not a production release), the charts
do not scroll smoothly etc and it makes the applications less than optimal so I decided to revert to my earlier build based on stable versions of OpenPlotter (v0.8.0) and OpenCPN
v4.4.0. I updated OpenCPN to v 4.6.1 so I could use the oeSENC plugin (v1.2).
I loaded my oeSENC charts but when I come to use them I get the message that the "UserKey entered is not valid for this oeSENC chart set". I had thought that the key was generated to identify the hardware
but that hasn't changed, it's the same RPi that the charts were registered for.
Do I need a new licence just because I've moved to a lower underlying version of software
? The licence worked fine as I changed version in an upward direction.
I mention OpenPlotter here only to explain the reason for my reverting to an earlier software
platform. It isn't material to my question.
