A quick look on their site
Q: Which forum system does it currently support?
A: Currently
phpBB3 3.0.x,
vBulletin 3.7.x/3.8.x/4.0.x,
Invision Power Board (IPB) 3.0.x and
Simple Machine Forum (SMF) 1.1.x/2.0.x are supported.
We are still on vBulletin 3.6.8 so it will not be possible until the forum has been updated.
