I downloaded my copy of NGX 2 days back and the installer file is still laming around my hard disk, I know its toooo much of a hard feeling to not try it but I've got a brand new plane in real life on my hands and need to get released on that first. BTW my question is, how long before my download expires, i have it downloaded already but just need this information as well. How long after buying can I wait before activating my product ? can I do that like after 2 weeks (not really going to wait this long but just wanna know) Thanks

Seven days until your download link expires. As for activation, I don't think there is a time limit on it.
