We were able to resolve this issue. The best that we can figure out is that a file became corrupted. This could have been the result of a virus scan (they use Webroot) or a Windows update. I had replaced the Sy_Personalize.M4T and the various M4L files in question. I restored those from a backup copy created when the system was first installed. This didn't work. I also restored the Sy_Console.M4T and that didn't work. Actually, as I said above, the Sy_Personalize.M4T replacement DID get rid of the first error box.
I stumped the Sage support people and they scheduled a specialist to look at it this morning. He agreed that there must be a corrupt file and we reviewed what I had restored. his next suggestion was to find the corrupt file in the ""Home"" and/or ""Launcher"" directories. Instead, we renamed those directories and restored backup copies from a snapshot taken immediately after the initial install. That cleared up the problem. I'm not going looking for the corrupt file but will be weary for the future.
