Negative cloud credits in student version

[anelso29]

I am trying to render an image out of Revit 2015, and I have a student subscription, so I should have unlimited cloud credits. Early yesterday I was able to render no problem. But last night, after moving from the computer lab to home, so I'm on a different computer, I started to get this message when trying to render  which has to be impossible. I'm still a student, my accout is still active. But I can't render at all right now. I don't know if this is the same any other computer. This only happens out of Revit, I can render out of Autocad no problem. What do I do to fix this? Thank you!
