Chaseplane preset removal?

I've got a bit of a catch 22 here. XtremePrototypes Lear won't load and crashes P3D due to some issue with Chaseplane. It had been running fine up until yesterday.

I know this as I've disabled both exes in the Program Files/Old Prop folder and the Lear loads fine. So, if I can't get the plane to load, I can't remove the offending presets that must be causing the problem :>)

So, can the presets for this AC be cleared on the cloud  side? Or reinstall?

Thanks,

Mark
