Unable to checkout a viewer license

I was given this license for free as a part of a course at my university. It expires in August 2026, but when I tried using it again after about 4 months, I'm getting an error message when launching Questa. The error message reads:

"Unable to checkout a viewer license necessary for use of the Questa Intel Starter FPGA Edition graphical user interface. Vsim is closing."

I tried contacting my university's IT department, and we tried debugging this error for around a week back and forth. After exhausting the common potential fixes like making sure the LM_LICENSE_FILE environment variable points to the correct path and trying to run the software connected to my school's VPN, we had no luck. We determined that the MAC Address of my machine was the same as that of the NIC expected in the license file except the last two digits of my machine are 11 instead of the 15 that the license file expects. This software worked completely fine for me when I took the course, and it was only after around 4 months that when I launched the product, I ran into this issue. The IT department said:

"Because you used the software through a Mines (my university) course, it was most likely pulling from a campus floating license or on the university's license server. You can either try to replace environment variable with LM_LICENSE_FILE=27000@ece-license.mines.edu while on the VPN. Otherwise, you will need to request a corrected fixed‑node license from Intel."

I would really love to solve this issue. I am happy to provide any other details that may help you to solve this problem!
