Hello,
Sorry for the issues.
We do not have a debug mode for the Facebook Events.
The errors that show up in the Importer usually give a good idea of what is happening and if not you can always ask as you are doing now.
I tried the event you linked and it worked for me.
I tried as well with this username: theatreatlittlewashington
That again worked.
Can you recheck your Facebook APP ID and Secret and verify they are correct.
If they are and you still cannot import events we can try our troubleshooting steps to see if we can find a conflict.
Let me know what you find out and we can go from there.
Thanks
