TF60014: The username {0} in the user map file {1} is invalid.
This error occurs when the username in the usermap.xml file is not in a recognized format.
To correct this error
Make sure the account name is written correctly with a backward slash "\". For example, DOMAINNAME\USERNAME.
Make sure the domain and username exist.
Make sure the domain controller is online. If it is offline, the account cannot be authenticated, even if it valid otherwise.
You can also get this error if the account you specify in usermap.xml is a workgroup account, but the computer that the account belongs to is not the same computer upon which the VSSconverter is running.
