Unfortunately, we are unable to assist in granting access back to your account, as your account is currently Disabled. This could be due to your current status if you had taken a semester off, Withdrawn from the University, or other similar situations. That said, if you are attempting to return to the University you will first need to complete the "Intent to Enroll" form with the Registrar.
If you have completed this within the last 48-72 hours, your account is presently in the process of being reactivated, and you will receive information to reactivate. If you have not done this yet - or it has been over a week - you will need to reach out to the Registrar to ensure that there has not been a processing error or they do not require any additional information. Their contact information can be found on this page: https://www.jmu.edu/registrar/students/reentry.shtml
