General Question UMMU initialisation message

[qkzkfkzkwlsh1]

I am using the latest Shuttle Fleet (with UMMU capability added) with an orbiter install (O2010P1) taht does not have UMMU addon loaded. This triggers the message "Shuttle ERROR UMMU 2.0 not properly initialised in your code" every time I load a scenario.
Is there a way to get rid of that message without having to install UMMU?

Thanks
