Nuendo Crash when opening project

Has anyone seen this before

Been mixing a track, all ok yesterday, tried to open today but Nuendo crashes and displays the error below. I have removed all vst plugs and it still won’t open (Inc alt versions and backups). I’m able to create a new project and add plugs to my heart’s content. Also no prob to open other existing project files. This is a nightmare as client expecting finished mix today! Any ideas?

Send me the project .npr, will see if I can open it here.

Thanks Fredo, have sent it over to you.

So, did you get it to work?

Yeah, no problem.
I could open the file without problems.
Did a Track export, so Andrew could import track by track, thereby troubleshooting the project.


A shot in the dark:
If you use Eucon, disable it and see if the error goes away…
