This error could be due to application or version definition corruption on the Repository (sfiles). Please e-mail the file created in the temp directory to support@todaysystems.com for help in determining the corruption.
Background: View the bad reply file in an XML editor. One of the application or version definitions will be corrupt. This will either be detected by the XML editor or by viewing the property values. The CenturyBase is a good place to look (it should be 1982).
