I did “purchase” the free packs before downloading and that’s when I posted my comment. However, I also came here with a workaround…
Restarting the game didn’t work. Nor did restarting the computer. This has been going on for days. However, I got a few of the last stubborn ones by downloading one, letting it fail, then selecting that one again, clicking ‘Cancel’, and then downloading it again. Might be a fluke/luck but it worked for 2 out of 3 of the remaining stubborn packs.
After I started having problems I definitely started doing them one at a time, which seems to help. Same with the trick above. There are still a couple that won’t work, which is too bad but they’re not particularly important to me. Glad I didn’t pay for them and that I was able to download all the stuff that was owed for the Premium Deluxe edition.
Thanks for the reply! Hopefully this will help someone else too.
