Azure for Students Subscription Renewal

Hello,

I'm unable to renew my Azure for Students Subscription as I get the following error message:

You are not eligible to renew Azure for Students  Sign up for Azure for Students Starter.

Unfortunately, I teach ASP.NET and Azure courses at my community college so this is a big problem for me.  It appears that at some point my subscription was changed to a free trial and now I'm unable to renew Azure for Students.  I have two expired Azure for Students subscriptions as well on my account.

I've tried Azure support but they were unable to assist me.  Any assistance would be greatly appreciated.

Thanks,

Joe
