Also having a problem downloading some DLC..
I've bought the Ultimate Edition from a retailer this week and just installed it by redeeming the code in my Origin client.
Installation of the game went smooth, just like the DLC that is included in the Ultimate Edition. So far no problem.
However...
Bioware website lists some free redeemable DLC as well, like eg. Pearl of the Anointed. I redeemed those, but the game cannot download these DLCs. It lists them and sticks to 0% and says "Download failed".
Triggering the download by clicking "Retry" has no effect. (Note: DAUpdater was running!)
Manually downloading the DLCs and installing them seems to work.
After having done that, the DLCs are listed "enabled" in the 'Installed content' tab, but also as "failed" in 'Download progress'.
