Confirm you are renamed BOTH files in this folder, like mentioned.
It should contain: LoadingIconAnim.dds LoadingScreen.jpg
@Erik Weatherwax your symptom implies you didnt rename BOTH files. If you remove the .jpg its still loading the animation, but you can't see it now, because the image is gone (at least that sounds logical)
@Florian Traverse again, you only mention renaming the .jpg so try BOTH files like mentioned.
$ ls betatest/retailclient/LoadingScreens/ LoadingIconAnim.dds.bak LoadingScreen.jpg.bak
Still no good. There is some speculation that the effectiveness of this workaround depends on whether or not one has prior characters in the game.
