Vintwood Theme Purchase Code from envato elements dosn´t work

[NEXTLEVELMedienagent]

I downloaded and installed the Vintwood theme from Envato elements. The License.txt downloaded under Downloads, in this version the Item License Code. But when I enter the code under Theme Option> Maintanance & Help> Maintanance> Theme purchase code. He writes to me in the CWS demo importer: Error: Wrong Purchase Code.

What can that be?

See my reply here:

You have purchased a license for some products, but the license does not work

The themes that you downloaded from Elements doesn’t come with the purchase code. You will have to purchase a copy at ThemeForest to get the updates and free support.
