I get the following error when monitoring my program (see attached screenshots):

"Unhandled exception has occured in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

Value cannot be null.
Parameter name: source.

And the details say:

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">
</system.windows.forms></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

The windows show red X's where the networks should be. Any advice on how to fix this?
