Screening Online API Request - Fault occurred while processing

We are receiving the error "Fault occurred while processing" when trying to make API calls on the Screening Online API.

I've tried contacting Thomson Reuters directly but have yet to receive a reply after two weeks of chasing.

Has anybody seen this error and know what is the cause? Nothing has changed in our processes as far as I'm aware, and previously this error was corrected by Thomson Reuters themselves.

Thanks,

Chris
