The error you are seeing indicates that Revit 2013 cannot acquire a license from the Autodesk License Manager. The fact that you are seeing this error indicates that the option to use a network license instead of a stand-alone license was enabled during the installation of Revit 2013, . If this is the case, there isn't a simple method to change the license type from network to stand-alone. In order to do so, you will have to uninstall Revit 2013 and the reinstall it, making sure to select the stand-alone license option on the Product Information page.
