The new ticket, in English or Spanish?
Got it. Really sorry for being annoyingly dumb.
#640533
It’s copy-paste from the forum, but it’s well explained. The description in English and the details in Spanish
I’ve realised now that I could open a product support ticket, not an order one. Because of this the solution may came late, but in this case it’s my fault.
I’ve recieved the ticket reply. It sounds good. They trying to contact me now
Doesn’t matter if it is in Spanish.
moroni speaks Spanish.
If not he better start learning it quickly ;D
He (or someone else from avast) will have a look at the ticket and soon help you further.
I am not working for avast, so I can’t promise you anything but you can expect a response within 48 hours from now.
And don’t worry about the end date of the offer.
I’m pretty sure avast will keep that in mind and won’t make a problem about it.
Don’t forget it is night now in Europe.
If they do what you said that you’re pretty sure about, that would be I plus for Avast! 
At least I want to confirm if I haven’t spent 600€ for a single license ;D
As I said, I’m not working for avast so I can’t promise you anything but knowing avast and how moroni handles things…
Yes, I’m pretty sure (99,99% as they say)
Y understand don’t worry… But the avast evangelists work here in the forum is huge
All of us are just people who don’t mind spending some of our time helping others with the knowledge we have.
The people who work for/at avast have “Avast team” underneath their name.
It is my native 
Hola! ¿tienes registrada tu licencia bajo otra dirección de correo electrónico? no pude encontrar ni tu licencia ni el intento de renovación usando el correo con el que abriste el ticket.
Le pediré a alguien que tome tu caso pero por favor envíanos la dirección bajo la cual tienes registrada la licencia y/o intentas registrar la nueva compra 
And sorry y’all for writing in Spanish here
Of course you haven’t found any license registered with the forum acount email:
xxxxxxxx@gmail.com
My license is registered with:
xxxxxxxx@hotmail.com
But don’t worry, the Avast support team has sended a reply for my ticket this morning asking for my order data. I’ve forwarded some screenshots of the Digital River confirmation email and my subscription page in the Avast settings.
They’ve told me that they’ll send a direct link to buy my license.
One off-topic doubt:
If I buy now my license using Avast Premier 2016, will it be valid for Avast Premier 2017? Or my program will just update itself when the stable version is released (I know that now there is a Beta)
I edited your message to hide your email address.
Our licenses are valid for the “edition” (Pro, Internet Security, Premier), regardless of the “version” (2015, 2016, 2017…) so there shouldn’t be a problem to use the next release with a license you purchase today.
Oops, forgot that we’re at a forum.
Ok. I’m waiting for the reply from Avast. If everything goes well, I’ll renew my license before the antivirus expires.
The antivirus has expired and I still don’t have any link from Avast to buy it… 
That’s not fair. Why I have to spend 90€ instead of 55€ because Digital River is failing?
