Dreamweaver CS5 fatal error web design

Hello everyone,
I have installed the Dreamweaver CS5 web design and HTML editor software. What I want to do is delete a corrupted .xml file. I successfully delete it but immediately after that when I open the Dreamweaver software again, a fatal error message appears saying:
XML parsing fatal error: Invalid document structure, line: 1, file: C:UserTylerAppDataRoamingAdobeDreamweaver CS5en_USConfigurationWorkspaceClassic.xml
