I have been attempting to download the new texture pack, and also earlier the Inspiration Island map. Both of them have said they were downloading, but their status did not change over an extended period of time. I have had a good internet connection, and plenty of space on my laptop to download, but it won't actually download at all, so I can't use them.
Thank you for your report!
