Evaluation Header still showing after buying the Licence

My company recently bought Aspose Word Writer.Before buying I was using evaluation copy.
There is a Visual Studio 2005 project on my machine that was using the evaluation copy. After my company bought the licenece, I installed ot on my machine and updated the DLLs in my project. but the Word Doc generated from VS project is still showing evaluation header. How can I remove that, since I have a licenced copy now.
