However, it returns the “Cannot import data as JSON format” error whenever I try to do this, as well as with some other similar commands. I’ve linked my Facebook account, and some other commands (such as FriendNetwork) work fine, although others return the same error. Clearing the system cache doesn’t change anything. Does anyone know how to fix this issue? Thanks!
The error that you got can come from a file that is not properly formatted JSON, which, of course, could be anything that is returned when, for example, an error web page is sent.
That’s an older version. I apologize. I asked you to run the wrong command. Run $ReleaseNumber instead. It should say “2” for version 10.0.2 which is the latest release.
If you get Mathematica directly from Wolfram Research, you most likely can get it from user.wolfram.com after logging in. Some universities have a different distribution system. If you run into any problems downloading 10.0.2, I would suggest contact Wolfram Customer Support (Contact Wolfram Support by Email or Phone).
