System.NullReferenceException: Object reference not set to an instance of an object.

[Riyshn]

On loading the plugin,, I get this message in the log:

3/21/2018 1:39:37 PM: Warning: LoadConfig: System.IO.FileNotFoundException: Specified file is not exists.
File name: 'C:\Users\Nicholas\AppData\Roaming\Advanced Combat Tracker\Config\RainbowMage.OverlayPlugin.config.xml'
at RainbowMage.OverlayPlugin.PluginConfig.LoadXml(String pluginDirectory, String path)
at RainbowMage.OverlayPlugin.PluginMain.LoadConfig()

As well as this error message any time I try to interact with anything in the plugin settings tab.:

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:

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.

For Anyone who gets this error, Make sure that the file you are storing everything for the Overlay plugin is not set to read only.
