I saw ZOS_JessicaFolsom in a previous discussion (
http://forums.elderscrollsonline.com/discussion/79528/error-209-after-patch#latest) tell us to delete all .version files in the game's sub folders and try repair again if the repair failed initially.
That started a 22gb download, so I thought it wasn't worth it and restored the three .version files from my recycle bin (Right click -> restore) back to their respective folders. This completely solved the problem for me and my friend, so it may help some others too.
