Okay, checked out the permissions and you're right, they have got messed up with the upgrade to win 10.
I have now changed the permissions to give me full control of My documents and checked the install of charts again which now works fine.
Thanks for all your help Tim.

Ok. The Spain chart unload thing is a bug fixed in the forthcoming 2.4 release; it isn't a big issue as once the software is restarted it's fine.
The running as administrator thing confirms my previous theory: Windows isn't letting SkyDemon write the data it needs to disk. I suspect this is an anomaly as we don't write anywhere we're not supposed to, so perhaps the permissions have somehow got messed up on your machine. As long as you have write access to your own Documents folder and AppData storage area (which you should have) that's all we need.

Another update....

If I select to run Skydemon.exe as Adminstrator then installing the charts is not a problem.

Okay, tried to delete the chart for Spain and recieved a different error.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.




I have also tried adding chart by using windows 7 compatibility settings (i was running win7 prior to the win10 install). This allowed me to successfully add and remove charts as required. So at least this is a work around for now.

That is unfortunate. It means there isn't anything for us to go on. I'll keep thinking about it.

Sorry Tim, Can't see one...

Is there a debug file in your My Documents\SkyDemon folder? That might include information if it's an error we can catch and analyse within SkyDemon.

This doesn't appear to be a general problem as lots of people have upgraded to Windows 10. I wonder if it's stopping SkyDemon from being able to write the chart data it's downloaded to disk or something.

Screenshot added in post above as per request.

I've added Italy and Austria with no problems
