I too have tried that and it failed, but i found something that works.
Find someone, a friend mainly, and this is very simple (if you use teamspeak) have your friend who has already updated to Heavenly Strike successfully upload the DWOnlineLchr.bin to the teamspeak, then you download, it is much faster than megaupload.
just replace the old one with the new one, then update like normal.
Then, Voila! you have the update!!
