Make sure the queue reference is valid…

Most likely causes here:

1. You did not initialize the queue.

2. You closed/destroyed the queue before this call.

3. Your FGV has a bug where the queue reference is not wired through a case and the tunnel is set to "Use Default If Unwired".  You should only have a tunnel set to that in very limited cases because of this type of situation.

4. You call the FGV that creates the queue in another top level hierarchy than this VI and that other top level hierarchy has since gone idle.

Reason: All LabVIEW refnums are auto collected (closed) the moment the top level VI in whose hierarchy they were created goes idle.
