Just to close the loop for others who might have a similar issue...
Linda identified the issue after looking at my output file.
I'd entered an Mplus command in my Title section. I titled the file Model 1, which activated the "model" command, which then caused the error message.

Actually the problem was that you had MODEL 2: in the Title command. MODEL 2: is the specfification for a group-specific MODEL command with label 2. Mplus commands should not appear in the Title command.
