[CLOSED] License problem

Hi,
today we have a runtime exception on our site, saying this: "LicenseException: Ext.NET license unlocks a different Ext.NET version."
We bought a premium license for 7.1 Ext.net Classic and I configured the license as specified in your guide.
Can you please help? I'm blocked with the development.
Here the error:

Attachment 25484

Just for info: I'm using Ext.Net Classic 7.1 and Asp.Net Core MVC 3.1

Regards,
Fla

Hi Fla,

You have been sent an email with your Ext.NET Classic v7 License.

The license key can be set in your app using the following instructions:

Hope this helps.
