Hello Francois,
We are running Brainstorm from Matlab. I tried what you suggested and installed the new OpenMEEG but I still got the same error.
This is the dropbox .tgz link for the error:

Do you have any other suggestion or idea with regards to how to run source localization with the ECoG and SEEG sensors?
Thank you very much for your help!
Michel
