'Subscription License has expired'

[TOyMan666]

When I tried to open my Pro Tools 12 yesterday it suddenly pops up with the window saying Subscription license has expired, and when I click continue it's requiring me to activate the product again. And after I log in, it says that I don't have remaining license left to be activated. I've checked my billing everything works fine on the avid web page, I've also checked the iLok license manager (already the newest version), and Pro Tools 12 shows to be activated in the cloud session. I can't deactivate it or do anything to it. I'm currently using the Student edition yearly subscription for pro tools, and it's really an urgent issue for me.
