If you encounter the following error message when attempting to upload an assignment, it usually means that your institution's Turnitin license has temporarily expired:
"You may not submit a paper to this assignment because the OriginalityCheck product is unavailable."
To restore your ability to submit papers, please take the following steps:
Contact your instructor immediately: Let them know you are receiving this specific error message and are currently blocked from submitting your work.
Wait for institutional review: Your instructor will need to liaise with your school's Turnitin Administrator to renew the license and reactivate the account.
