If you get an error like this:
The Singleton class SOMECLASSNAME has multiple instances.
This means that for some reason, there is more than one object of the class that is marked as Singleton - and there should per definition only be one.
To fix this, start the MDriven OCL Debugger towards the same database that has the error.
