Hello,

I'm trying to export my distance constraints to cns with the format converter, 
but I'm only getting the following error message:

"Error while exporting file: /path/to/file.tbl"

I'm sure that I've have write access on my destination path.

Maybe more details on the console:

###############################################
# FormatConverter: executing writeConstraints #

So, what's wrong here? Or have I forgotten something crucial before the 
export?

Marco
