I figured out what was causing this on my end. When the system patches at launch it creates 4 files and a folder on your desktop. If you delete those the launcher will do a complete download for your patch.I tested this yesterday, on a hunch, and with those files in the Recycle Bin the patcher created 5 new files/folder on my desktop and said there were over 160000 files to download. I immediately bailed out of the patcher, deleted the new files on my desktop and went into the Recycle Bin to restore the original files.As soon as the patcher launched the Launch button became active and no download started.I dont know if there is an alt solution to this for those of us that hate clutter on our desktop so any more information to get around this would be appreciated.
