Thanks, Chris.

I received a similar message today when using PROC EXPORT. At first I thought there was an issue with the file path, as SAS was printing two forward slashes to the log. But that seemed to be not an issue as is mentioned in this SAS Communities forum thread.

However, nobody had the file open. Since my PROC EXPORT would create the file, I deleted the old copy, closed and reopened SAS, and it worked fine.
