The license file is not applicable

Hello.

I purchased Aspose.CAD for .NET products in 2016-12-26.
The expiration date for this license is 2017-12-26.
I’m going to use the Aspose.CAD for .NET(ver 16.10.0.0) published in 2016-10-06.
I was download license file in “Order Review” page.
However, this license caused a “The license signature is invalid” error.
How can I apply this license?

Thanks.

@dev9,
Hello.
As I can understand you are trying to apply the new license file generated now for old product 16.10, is it right? Do you have the old license file generated in 2016? Please follow this example and send me both license files (if you have old one) so we can test this issue.

I did send message to you.
Please check.
Thanks.
