It was running fine for months, now it doesn't run at all.  I also updated from 11_7 to 11_9 to see if that would help.  Defender is disabled and I have no other virus scan.

Please let me know what I can provide or do to start troubleshooting and get this thing back running.

THanks in advance,

Nakia
