Xively - An internal server error has occurred - what's happenning?

I registered at Xively a few days ago and created a device. But when I log in and click on my device, I get the message: “An internal server error occurred”. There is no further explanation and I could no forum at Xively to ask about the problem. My imp works just fine and has no problems that I know of. The Xively error has occurred for several days, so there must be something wrong but I have no idea what it is or how to find it. Does anyone have any idea what the problem is with Xively?

Thanks for any response.
