Purchased a realm and then got an error stating that the purchase was successful, then it tells me I need to finish setting up my realm. Then it says, sorry couldn't creat it right now or something of those lines and to check back later.

Pretty much as was stated in the summary. Made the purchase for 7.99 version of realms. Started to set it up, then it said that my purchase was successful but they couldn't finish my realm and then told me to check back later.
