Hi there - Dragon Valley is my first download purchase, and I'm also experiencing this issue today.
I've tried IE and FF, and have updated my base game and restarted my computer a few times. I attempt to download from the "my purchases" screen, and to answer to your questions:
- I eventually get a message from the Sim 3 Game Launcher that states either "There was an error downloading content. Please see the log for more details" or "We're sorry but you do not own the content that you are trying to download"
- Base game is updated, no further updates available*

Any advice on how to actually download this world would be much appreciated.
*Edit - after restarting a few more times and turning on the option for automatic updates, I found another update that took me to version 1.55. It now looks like it's downloading...
