Ok, now I found out what happened.

I looked with vim into the .omniplan file and actually it was not an OmniPlan file anymore. Instead it was a pdf file. I remember that I exported my project as pdf just before I saved it the last time. And somehow OP got puzzled and changed the default file format into pdf instead of omniplan file format.

Hopefully this bug has been solved in the latest RC.

Cheers,

Jan
