All my work is gone

Hello ! My subscription ended and I thought it would renew automatically. 
My subscription WAS NOT renewed. 
It was apparently a 1 year not renewable subscription (students). 

The problem is that all my work is gone. I need access to all that work, all that proof of work and capability.

When trying to access 3DS : Felix LAVIGNE DELVILLE is not able to connect because licenses have expired. Please check user details in Platform Management on platform: LAVIGNE DELVILLE_F - OI000355514. But when I click on that link, it lands on a disclaimer : You can't access 3DEXPERIENCE Platform.

I just want to export all my work... That's a big problem right now Please can you help me ? Thanks
