SDL Language Cloud

Hi,
I have used SDL Language Cloud (between Danish and English) successfully until yesterday, but today it no longer works. When I try to add the Language Cloud in project settings along with my TMs, the Cloud window displays no AdaptiveMT model for the source and target languages, and the Manage AdaptiveTM models box is grey and cannot be activated. Is it just a temporary maintenance issue, or...?
Best regards, Bo
