We are aware of this issue where some of you are seeing the launcher as "stuck" at this specific point of 249 megabytes remaining with this recent update. Your update is not frozen. It's processing a very large file in the cache which depending on the speed of your computer and internet connection could take a while. Restarting the process over and over, or re-verifying the cache, is not going to help you out. Please just be patient and let the game work. As others have noted, it may take upwards of half an hour.
