NBC sports extra has been giving scripts errors today..... the fix is attached to this post.
I have attached the file itself, and also a new zip file for those who want to uninstall the version they have now and install it again with the fix already in place....
If you want to apply the fix manually follow this path.... \Kodi\addons\plugin.video.nbcsnliveextra\
If using it on the Wetek with openelec follow this path..... storage\.Kodi\addons\plugin.video.nbcsnliveextra\
All credit goes to DJBlue for this fix........
