Dear Fernando,
There seems to be a problem with the online database that SAM connects with to download the data. (The dataset is described in this
OpenEI blog
.) I will post another comment here when we resolve the issue.
Best regards,
Yes, this issue was resolved. I just tested the macro today and it worked for me. It is possible that the OpenEI servers were temporarily down when you tried. Please try again and let me know if you continue to have trouble.
Also, please be sure that you are using the latest version of SAM.
