PROBLEM I am getting the following error when I try to start PR-Tracker. <?xml version="1.0"?> <ExceptionInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Message>There is an error in XML document (0, 0).</Message> <Product>PR-Tracker</Product> <Version>6.0.738.0</Version> <Configuration> </Configuration> <EventList> Start Program </EventList> <SignatureCode>664664</SignatureCode> <Trace> There is an error in XML document (0, 0). at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader) at Prtracker6.Helper`1.LoadFromXmlFile(String pathname) at Prtracker6.Program.ReadSettings() at Prtracker6.Program.Main() Root element is missing. at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.ThrowWithoutLineInfo(String res) at System.Xml.XmlTextReaderImpl.ParseDocumentContent() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlTextReader.Read() at System.Xml.XmlReader.MoveToContent() at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderSettings.Read8_Settings() </Trace> </ExceptionInfo> SOLUTION This error is occurring because the PR-Tracker Settings.xml file has been corrupted. To recover from the error, delete or rename the file. The location of this file varies depending on the operating system. On Windows 7 and 2008 you can find the file in the folder C:\ProgramData\PR-Tracker.
