Cubase stopped workin

hi,when i close down cubase,i get the Cubase hasstopped workin" error message,and i have to click “close now” to get it to shut down.
any clues? im on 6.0.6

Probably a dodgy VST plugin? Are you running any third-party ones or just the Steinberg ones?

running 3rd party plugs.

i just actually happens,say i boot cubase.dont open any projects,then just close cubase. i still get the error box.
