Language Cloud not working

From one day to the next, I am not able to use SDL Language Cloud as a TM when I am translator in Studio. I have always been able to do this. I received a message that states, "The translation provider 'SDL Language Cloud Machine Translation' does not support any language pair in this project or project template.". However, this is not true. The project has my normal language pair. I have logged onto my Language Cloud account and it is active. Please advise.
