Exception Thrown In SetLicense

Good day,


I am receiving an “Object not set to the instance of an object” error in my control. It occurs on the “SetLicense” method. It looks like the LIC could be invalid based upon previous posts I have seen. We purchased the product on 4/12/2012 so we should still be live with our subscription.

Please Advise

Thank you and have a great day,
Adam Macaulay

I have received the license file and have worked with that using Aspose.Slides for .NET 7.1.0 and have not been able to observe the issue specified. For your kind reference, I have attached the sample presentation and generated output. Please share, if I may help you further in this regard.
