Is there any way of getting the email sent again?
If you haven't had an email it's not the end of the world, as with the old site all the info you need should be on the new one. There is a known issue with the email server, it's a bit hit and miss as to whether you receive emails from N3V or they go missing, doesn't seem like N3V have fixed it yet if it is something they can.
Log into account.
Recent orders will be displayed, click view order, serial number should be there.
Alternatively.
On the Left click My Orders, click the relevant order, serial number should be there.
Downloads are again on the left, My Downloadable Products.
If for some reason there is nothing there when clicking the links but your orders show completed then raise a ticket.
Links on the left are an orange red colour, I'm beginning to wonder if some can't see them, due to perhaps changing default web page colours with a browser add-on? Or perhaps a browser incompatibility problem with the website or some browser or paranoia add-on setting to do with security as one or two are saying there are no such links.
There definitely were when I checked, even if you haven't ordered anything. I checked the site out thoroughly before ordering to make sure it was similar to the old site and had links to records of your purchases. The links are still visible to me.
