cubase 6 crashes every single time

hi there,i’m in deep desperation and frustration!!
for some reason cubase crash,with this massage

i tried exporting all the channels and then open new project and then importing them back thinking the file might have been corrupted or somthing,but it crushes again and again.i will be so thankful if someone will help me up with this :neutral_face:

First, try deleting the preferences (see the knowledge base)
Then, remove all third party plug-ins
Then, reinstall Cubase.
