Hey folks, sorry about the download problem. What good are the textures if you can't download them, right? Heheh... That was my bad - I knew that bug was there, but completely forgot to fix it before I launched the site yesterday.
Anyhow, I've uploaded the new version of MediaGallery that should fix the problem. I'm able to download files now, so give it a shot and let me know your results.
Thanks all!
