Hi,
When I was collecting data from FB post, the following window jumped out.:
How can I fix it?
[NullReferenceException]: Object reference not set to an instance of an object.

Hi,
I have been having the same problem. It has happened several times when trying to download from the Facebook Fan Page importer. I have the following options selected:
Network
Vertices: User
Relationship: Comment
Create and edge between: Users who commented in the same post; Commenter and post author; Two consecutive commenters; Commenter and comment author

The same occurs even when network is not selcted, when none of the edge optionsa are selceted and when 'Post' is selected instead of 'User'

Any advice much appreciated.

I am also trying to download over a period of time, rather than a set number of posts. I have tried 2, 3 and 4 week periods but still no luck.
