Thanks for posting on the forum.
Unfortunately, there is no way to recover your work once the license has been expired, and it should be noted that students should re-apply for a new serial no. before the expiry of their current one has passed.
As such, please apply for a new serial no. for the following academic year at this link – https://education.itwocostx.com/support/forum/educational-request/
Thank you again.
