My University gives us access to Mathematica software for a computer if we need it for a math class. I downloaded and, per the instructions, went and signed up for an account using my university email address. However, it said at the end of installation, I would receive a prompt to enter an activation key, but I never did, I had to open the application to get that prompt, and even after registering for an account with Wolfram, I never received the activation key. I'm not sure what I should do, has anyone else had this problem?
