Try the following if you have not already, as it appears that the communications line to that generator is not 100% functional.
While Spooky2 is shut down, unplug the USB cable to that affected generator. Power down the generator for a bit of time, power back on.
Replug in the USB cable and allow the OS to re-establish the driver link.
Start Spooky2 back up and see if this fixes the issue.
If not, for whatever reason, your COMS chip may be blown. Installation of the spare COMS chip may be the next thing to look into if nothing else works.
