Plugin – Jetpack- twitter timeline widget disappeared

Hello!
I am a blogger at http://danceflowlift.com
I used to use jetpack with Weaver II theme and have now moved over to Wearver Xtreme, this seems to have wreaked havoc with widgets, all of which I managed to fix apart from my Jetpack Twitter Timeline widget! If you look on my site, on the sidebar there is a large empty space before my instagram feed, this is where it should be! I have removed it (which weirdly caused all my other widgets to disappear also), put it in different place, and created a new twitter widget and deleted the old ones, all to no avail.
Any ideas on this greatly appreciated. I’m not very tech / code savvy, so apologies if this has an obvious solution…or if this needs to be in the Theme forum.
Thanks
Natasha
