Issues with FEM tutorial

Can we use Duneuro without internet conection?

Everytime I try to compute a head model with Duneuro it gline it gives a error warning:
"could not get current online version of bst_Duneuro"
(or something like that),
@Francois explained me that is because of a SSL Brainstorm site certificate trouble, but I had already Duneuro installed, so I was wondering if there is a way to use it without the internet issue

Thanks in advance!
