Thanks for the suggestions. Unfortunately, I got impatient and copied the files over anyways. I also manually copied over the XML file from the new ServicePack to see if that would help - neither worked.
I then waited for this morning to see if anything happened - still nothing.
Finally, I upgraded my SIM instanace to the August 2016 patch and now I am waiting for things to settle down from that upgrade. If that still does not work I will try your suggestions.
Thanks
