Pay Super Set Up Error

Hi,

I am trying to set up Pay Super for a client and I keep getting an error message at the end once I have hit submit. I have tried over the last few days thinking it may of just been a glitch on that certain day, have also tried through web browser. All the details are completed and no other errors have come up.

Is this a known issue that is happening at the moment and how can I fix it? 

Below is the message I get.
