Hello Igor

I don't know if something like this can be achieved, but before I can forward the question to our developers, you need to have a valid license.

You can retrieve the invoices by following this article on Envato. Depending on the date of purchase, we can provide you with a discount coupon so you can switch over to one of our licenses https://wpdatatables.com/pricing/

So, just send me the invoice (in a private response), and I'll see what we can do.

Hi again Igor.

All previous purchases from Envato are registered there, so there has to be a trace of this purchase in your account. People have been pulling invoices from 2015, 2016, so it has to be there.

We can't provide assistance without proof of purchase.

Hello again Igor.

Our developers aren't quite sure what you need exactly, but you can try wrapping your logic in load event with jQuery: https://api.jquery.com/load-event/

Please note that this is a custom solution, so it doesn't fall into included support for the plugin. Even if you were to switch to our license, our developers wouldn't be able to custom code it for you, because we no longer provide customization services. Our support refers only to advice.
