LRS Track/plug Error

None of my projects will now load in X2 without white screening the app.
If I 'safe load' a project the project will load if I click 'no' to loading 'LRS TRACK: GROOVEPLAYER'
From forum searching I see this could be to do with the audio metronome but I'm at a loss what to do.
Worse still, the posts on the subject seem years old so am I the first X series Sonar user to be plagued with the return of an old bug??
 Any help fixing this would be gratefully received as clicking yes a thousand times and then no once is getting damn irritating!!
 
Cheers.
