Aspose.Pdf 1.9.0.0 problem

My WebApplication (dev environnement) generate an exception when I try to execute the folowing code :

Doc = new Pdf(System.Configuration.ConfigurationSettings.AppSettings["ConfigPath"] + "Aspose.Report.lic"); //The file exist and valid on TestServer

...

System.IO.MemoryStream Stream = new System.IO.MemoryStream();

Doc.Save(Stream);

Save Method throw an exception : Sorry, there is a problem with Aspose Unlimited license. AssemblyCompany of your assembly does not match the license.

AssemblyCompany is the same in all environement ( DEV and TEST environnement) and correct.
Dll version is the same (DEV and TEST environnement) : 1.9.0.0

All posts in your forums use a recent version of Aspose.Pdf with License class. I don't have this class and I cannot apply a new version.

How can I solve this problem ?

Thanks for considering Aspose.

I guess this problem may be caused by you older version. Please contact our sales department for free updating license.

How can you explain that the same code work fine on Test server and throw exception on my local machine ?

It seems the old license mechanism also check the machine name.
