Issues Getting Activation Email for New Student License

I was wondering if anyone knew of a fix for this, knew what the issue might be, or might be able to give me an idea on how long requests usually take to get follow-ups. 

I am an ongoing student at Purdue that has been using Substance Painter's student license, but my current license is from the previous now discontinued license system that does not update beyond 8.1.3, and I need to upgrade my license so I can have access to 8.3 for file sharing with another student in our team. 

The issue I've run into, however, is that when I go through the student request/free trial education version pages (substance3d.adobe.com/education) I go through putting my email and get the confirmation the request went through but then never get a followup email confirming eligibility or asking for further details if they're needed. Nothing in my Junk either, and I also know adobe emails go through without issue because several have for other reasons. 

Is there a different method to have the request go through or is the free trial/education license page the only means to send the request? Or is the issue merely that the request takes a long time to be processed and followed up on? Because it has been about a week now since my initial request, and I have resent the request a couple more times too in case there had been an issue with the first one.

I've also tried it with both my school email and a personal email in case but neither ever got a followup. I do still have a few months left of my current license from the previous system that had been disontinued around August of last year, but since I can't open files from my teammates' newer version and am not able to update passed 8.1.3 with my current student license version I'd prefer to be able to get this sorted and update my student license sooner rather than later.
