I purchase a season pass and I have completed the downloaded but unable to play my pass.
Hey there. It appears you own the Annual Pass but don't own Forsaken. You must own Forsaken to play the Annual Pass. I recommend asking for a refund then purchasing the [url=https://www.bungie.net/7/en/Destiny/Buy/Detail/forsakencompletecollection]Forsaken Complete Collection[/url] instead. This collection includes Forsaken, the Forsaken Annual Pass, the base game, and the Expansion Pass - all for the [i]exact[/i] same price that the standalone version of Forsaken was. If you own some of these already, don't worry - you won't have to redownload them or own two copies.
Which season pass are you referring to? Do you own forsaken?
