License not working

[Gonzalo Reneses]

Good afternoon.

I wanted to ask you about I problem I´ve had trying to install a better version of AMPL. 

I received the message of the attached picture thanks to my teacher. Then, I downloaded the installer, everything worked fine, it asked me for the UUID code and everything looked good.

It was when I tried to solve one of the problems that it told me that this version wasn´t capable of handling more than 500 variables, something that already happened with the first version I had previously, and which was the reason why I asked for this better version, though it looks like it doesn´t work.

Do you what is wrong?

Thank you in advance,

Gonzalo
