All my assets are optimized and updated. Perhaps you are experiencing problems due to the fact that the amount of assets is large and you do not have a first-class ticket to boot.
Part of the assets is confirmed, and some (including affiliates) expect them to confirm until a week or more.
When I ran into the problems with your assets, I had about 25 to download. I have a 6MB/sec DSL line and a FCT, and all other large assets I downloaded downloaded at high speed.
