I just received an email saying that my EST NOD32 Antivirus license will expire in 14 days. I have 2 licenses, one was for a desktop that hasn't worked for about 9 months and the other is for a desktop that still works. I don't want to renew the license for the non-working desktop but I do want to renew the license for the working desktop. How do I know which license I'm renewing?
