Change of domain for easyblog subscription

Hello,

I'd like to change the domain for my easyblog subscription. I changed the domain for my homepage from http://www.tobias-knaack.de to http://www.diekloeper.run.

My homepage is reachable with both domains, but when I want to install an update I am told that my domain is not registered. The address that is mostly used is http://www.diekloeper.run

Thanks in advance
Tobias Knaack
