Blizzard recently updated the HTML of the pagination so the threads are currently only able to download the first page. I have posted a fix to the App Hub and the update should be available in the next few days. I apologize for the inconvenience!

I am working on a change in the underlying engine so that the HTML configuration can be downloaded on the fly from my server rather than being hard-coded in the app. Additionally, I plan on adding functionality to allow you to directly access the URL of each forum and thread, so if this happens in the future you will be able to copy and paste the value into the web browser and view it manually.

In other news, I have ported all of the latest engine changes to WoW Forum Reader Lite, and am currently in the process of doing the same for the paid version. This allows for better performance, tombstoning, and other optimization features that may the app quicker for you to use.
