SocialNetImporter - network couldn't be obtained

May 19, 2015 at 12:56 PM

I've been trying to get the FB fan page data for 82942783549 after successfully managing a number of others using same settings. Unfortunately I get the error message below (at bottom of post).

I'm using Windows 8 and have tried doing this with SocialNetImporter 2.0 and the earlier release, within NodeXL (and prior to that trying

Many thanks!

can you please specify the settings you selected (a print screen of the dialog box would be perfect).

Hi Arber

Many thanks for getting back to me. I emailed a screengrab to socialnetimporter [at] (can't seem to paste them here), but the gist of the settings was:

checked for vertices: user, post
checked for relationship: like, comment
create an edge between: liker/commenter and post author, liker/commenter and comment author

Download from post 1 to post 50
limit nr comments/likes per post to 50
include also poasts not made by the page owner

Best wishes
