LMI Pro Login Error Message

I have used LMI Pro for years without incident. Today, I received the following error message when attempting to Login to a remote computer (that I have logged into hundreds of times):

Sequence of events: Log into LMI, select computer for remote access from list of computers, select File Manager, then when I enter my password on the remote machine ...

500 Server Error (0x5aa)

dashboard.html
System error: Insufficient system resources exist to complete the requested service. (1450)

WIN10 16 GB machine at home, so I suspect the remote machine may need to be restarted.

Is anyone familiar with this error message?
