We run DataXport on Windows2000 Server. It stops almost every day, with the message "Run time error ....... Could not save, currently locked by another user". It seems that it has nothing to do with the Excel file, because the Excel is always created, and DataXport still runs. It seems more as if some automatic log file cannot be written. The sw version is 3.0.1 , but it has been like this with previous versions. DataXport runs under an administrator account. Any idea ?
