Thank you for the file.
I could open it without any problem (see screen capture below).
Make sure your version of Brainstorm is up to date.
If your version of Matlab is too old to support the features in the Nicolet reader, try running the compiled version of Brainstorm (see the installation page on the website).
If you can't get this to work, please post more details about your system: operating system, Matlab version, full error message...
