Hi Aspose Team,
We are using aspose.pdf dll version 126.96.36.199. We have proper valid license key for that and it is still valid for another 1 year.
But when we tried to update this dll with latest version 188.8.131.52. We faced one error.
The subscription included in this license allows free upgrades until 09 Dec 2012, but this version of the product was released on 10 Mar 2013. Please renew the subscription or use a previous version of the product.
What we need to do use this latest version of aspose.pdf dll.
