Typically after you claim a package and go back to the software – if you are logged in – it should automatically detect your new packages and download them. You can always try to manually restart if this isn’t happening for you.
I just checked our backend and I can confirm that the pack is associated with your account. I also see several successful logins from your end, so there shouldn’t be any issues. The pack is available under the Season #1 packs icon btw.
Please let me know if you face any other issues.
