transfer subscriptions on same URL but different hosting

Hello,

My hosting provider changed some settings after which the Jetpack plugin could no longer connect.

On wordpress.com this gave an error ‘Jetpack 3.3 is required. Update now.’ And something like ‘An error occured retrieving your site-settings. Make sure Jetpack is updated’ (but than in Dutch).

I now changed to another hosting provider (maintaining my own domain http://www.degoudenhefboom.nl) and everything works fine again. Only on wordpress.com I now see two identical sites referring to http://www.degoudenhefboom.nl…. with one still showing errors.

How do I remove the ‘old’ sitelink?

and second:

When trying to go to go to ‘settings’ I still keep getting the errors above even though I already am running the latest version of Jetpack AND on the site the plugin works just fine and confirms being connected to wordpress.com (and is fully functional like f.e. showing the statistics etc).
