this is the answer i received from alienware arena:

"Hello,

A site error occurred for some users as keys were being assigned for the AMD Never Settle Forever Silver Key Giveaway, causing the same key to be assigned to other users. Unfortunately, as much as we would like to be able to provide a replacement key, the giveaway has a limited quantity and all keys have already been distributed. We sincerely apologize for the inconvenience this issue has caused you. Should we receive any additional AMD Silver Keys, you will be sent a replacement key.

Thank you,

Alienware Arena"

:D

First of all, they forgot to announce the fourth wave on twitter and they added 250 more keys, so AMD obviously has more of them.
Also, if we assume that some people received the same key, then some have received two keys? Or what happened to those?

They don't have to give you a working key if you only got one caused by a systemfailure and in fact should never have received one.

Yeah that's the answer

I sent them an email, and received the same message.
But it was a giveaway, and I didn't lose anything, so I can endure it.

You see, they can't give you another key coz there must be 1k keys = 1k winners. And some people are 1001 and 1002 winners. So, you won "by mistake". That's what I think.

Yes your math is correct 250x4=1000 but they forgot to announce the last give away so added another 250 that they announced.
"AMD Radeon Graphics ‏@AMDRadeon · Feb 27
@xxxxx Due to technical difficulties our post didn;t go out yesterday, we will be giving another batch away Feb. 28 to make up for this"

I'm in the same scenario, I've messaged AMD about it too but not got a reply as of yet.

AWA is the worst place to give keys like those. Their system is unfair and exploitable. I would prefer a system like SG where winners are chosen at random. Well, I think AMD learnt their lesson. They won't be letting AWA host any of their giveaways again.

same thing happened to me when i bought AMD CPU, they gave me an already used code

Honest mistake, and it was free anyway, so just let it go. My sympathies, though. Must be tough to go from the high of winning to the low of realizing the key doesn't work.

You reminded me that I must go dislike and unfollow their Facebook page. :P

Thanks!

Maybe a error of the page, but if they refuse to give new keys to the people who have problems with that
it means they not give 250 keys maybe... and this means it´s a fake giveaway...

GIMME FREE STUFF DAMMIT I EARNED THIS

LEL I got the keys :B1:

who cares, nothing but bots were raping that event at AWA anyways
