Hey there @abdu266, thank you for taking the time to get in touch and I am sorry to hear that you cannot find your full copy of Rainbow Six Extraction. In the future, can you please consider creating your own thread if there isn't something active already regarding what you have mentioned? Updating older threads raises forum traffic and clutter unnecessarily and moves more active threads down the page.
That said could you please let me know what platform you are trying to play the game on? If you are on PC, it is important to note that in some cases, there can be small delays and it could take up to 48 hours for your game to appear in your game library. If after this time frame, you still do not have access to your game, let me know and I will gladly investigate it further.
