When attempting to register a token credential, an error occurs
VIP Error: Failed to register Symantec Credential. Credential is not valid
The token credential is not associated with the client.
From the VIP account manager, search for the Token \ Credential ID. If it is indeed a VeriSign\Symantec credential, and it cannot be found in the VIP Manager, contact technical support to do a system search and determine the state of that credential.
