I have a similiar issue, but was unable to access my content by use of the suggested solutions. I just purchased a new mac, and downloaded origin. The base game started installing right away, and once this was finished, nothing happened. I thought maybe my expansions (and I have purchased every single one) had been downloaded as well, so I started playing. Once the game was open I got a message informing me that all material was not yet downloaded and that I could press ctrl + 1 to see in origin what was downloading. But there is nothing downloading in origin.
When I go to my game library, and click on more, all purchased expansions are listed as purchased, and I have the options of "download" and "purchase as a gift". Obviously I have pressed download on every single game.. but nothing happens. I have tried to uninstall origin both the hard way and the easy way, but nothing will trigger a download, its the same all over again that the "download" button is available but nothing will happen. I have also tried re-installing sims 4 base game, and I have tried both updating and repairing the game, but this does not change anything.
In the game, all icons of the games are colored and not grey. But when i go to CAS for example, I only have the base game content. When I go to expansions, I am informed that the content is unavailable for all expansion packs.
Please help me!!! I cannot even purchase the games again, as they are all listed as purchased, and i do not know what to do. None of the expansions will download, so i only have the base game. I have tried contacting EA, but when content is lost, there is no contact option. I have listed it as a bug, but I am informed that they wont send me personally a reply, they will only read and note. But that wont help me.
