Here's an error I got when trying to use this plugin.

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** 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.

Also when clicking continue and ignoring the error and trying to load a csv it says

Unable to generate heat map. Error: Invalid JSON primitive: access.

[VE3NEA]

Fixed.

[root-reindeer-flotilla]

Sorry but it's still not working.

SDR# version is 1666 and I'm using windows 10, sorry I forgot to mention that before.

[VE3NEA]

Here is a better fix. The problem was occurring only when the heatmap was not loaded, but the plugin was enabled. The UI is not supposed to allow this, I am wondering how you managed to enable the plugin that had no heatmaps in the list, or no heatmap was selected.

The fix ensures that the plugin panel is repainted properly even in this situation, but I would like to prevent such situation from occurring in the first place.

[root-reindeer-flotilla]

I have a few heatmaps that I've done, but the problem is I don't actually know how good they are until I visually see them.

It works! I did a wideband for an hour last night and that one seemed to have worked.
