Need your help urgently, can't log into MS ( Never had this issue).

Yup, I tried downloading the game with the downloader I had n my computer before, now I'm trying to re-download the game entirely from the website, namely: downloading the downloader again from the website.
Hope it works, even though I think it's not the problem. Seems like something on my comp keeps blocking the game.

Renew all firewall and anitivirus exceptions you gave maple (and if you haven't done that, add maple to the list of allowed programs in your firewall).
I've had this problem multiple times right after an update and that usually fixed it.
