Evaluation Message in pdf documents

Hello from France,

We purchased Aspose Total for .NET at the end of last year. We generate pdf documents from website for our users but we still experience a stange behaviour : When the document is generated the first time, the evaluation message is written, but when the document is generated once again, the message disapears ! Why does the message is still visible whereas the server uses a valid license from Aspose ? Could you check please what's wrong with the license ? You can reply to ddhordain@francelot.com

Thanks a lot Regard,

David Dhordain
