We need the new release of Aspose.Cells for .NET. We currently have an OEM sit subscription and are at v4.7.1. Our serial number is 229116a3-5565-4875-8013-a0de01e1a52b.
I did a live chat with someone at Aspose the other day and was given a download link. However it appears to be just a trial version. Can you please send to me the link to download the full new release, v4.8.1, along with any adjustments to our serial number or a license file if that is required.
As per your license issue, if your license is not expired yet (you may check the subscription expiry date in the license file by opening it in a notepad), you can use the same license file with the latest version of the product. If your license has expired then you have to renew your subscription and you may contact our sales team in Aspose.Purchase forum. Following is the link to Aspose.Purchase Forum.
