Error code ' Sender has not accepted terms of use

I am the Admin for Salesforce.com at my organization, and we have a contract process that sends out Echosign Contracts designed in Conga Composer.  A new team member claims she cannot send a contract because she gets an error message stating she has not accepted EchoSign terms of use.  What does she need to do to sign this?  As an Admin, I'm not sure how to resolve this issue for her.  Any tips are appreciated!
