@tamekaws,
It looks like you don’t have sufficient rights to post a private message (with attachment). Anyways, in the mean time, could you reproduce your issue in a simple (separate) application. Please create a simple console (application), zip the project and post us here to show the issue. Please do not include your license file into the zipped project as we will use any other valid license (by placing it as per the SetLicense() method path) to test the scenario/ case on our end. Moreover, I think the issue might be on your side, I suspect the licensing code is not processed at all, so you should debug on the module of licensing code in your project (e.g place break points on the lines of code) if the lines are processing or not. For your information, the licensing code should be processed first and evaluated at least one time in the whole application life cycle. Furthermore, if your license was not valid or already expired but your licensing code was processed, then you will get a warning message/exception to denote that your license was expired to use the Aspose.Cells version.
