If you purchased Crown Packs on Steam, but do not see them in game, you should ensure that you have linked your Steam and ESO accounts and that you have logged in using the Steam client. Please wait 24-72 hours for the arrival of your crowns from the time of purchase. If you are playing on the EU and recently linked your Steam Account, it is possible that it did not properly link. We recommend logging in briefly to the North American server, which should complete the link if it did not link previously.
Just so that people are aware, I've been having a problem on the Zenimax version for several weeks now. My character's movement will randomly slow down, when I do anything that isn't movement or combat, such as getting crafting materials, talking with an NPC. Going in or out of a door, etc. It may happen once in several hours, or a few times an hour. I am buying the Gold version that works on Steam, and will be linking accounts. It will be very interesting to see if I still have this problem on Steam.
