subscription confirmation link not working

I have just installed sendpress and all seem to be working well except on the confirm subscritpion link

This is the link sent to the email …
http://peacingtogether.org/sendpress/eyJpZCI6IjEiLCJsaXN0aWRzIjoiMjYzIiwidmlldyI6ImNvbmZpcm0ifQ

Which return the message “nothing found”

Have I missed something?

Thanks
Sam
