Hi,

I renew my student license from Zemax, but I cannot use the license number. 

What happen is that I don't see my old license to choose on the list, and in the email I have “License Update Code” which I cant use anywhere! I’m guessing I have to retrieve my old license somehow and then update it. 

I deleted Zemax from my computer, and I think that is why I don't see the my old license anymore!

Would anybody please help me to figure this out?

Thanks

Abbas
