Can you describe more details?
- What kind of file did you want to open?
- Which version do you use?
- Is it Linux or windows?

Looks like the Job Manager settings file(s) have been corrupted somehow. Unfortunately this happens now and then, and can usually be resolved by removing the "job" files in $HOME/.vnl/job_manager_<version>, and if that doesn't work try to also remove the "state.hdf5" file.
