Used this all year without issues but since 11-Aug-15 I've been getting following error - any ideas what is problem please?

ERROR: Couldn't retrieve and/or process financial data from internet service. Internal message: The remote server returned an error: (400) Bad Request.

Working again 24 hours later, must have been some error at the Yahoo end that was fixed?
