Registration failing after update

Just downloaded an update as I was prompted to upon opening Scrivener a few minutes ago. I was then prompted to resend my serial number, and it failed. Do I need to buy a new serial number for the updated software, or am I just having technical difficulties?

Hi,

No, you certainly don’t need a new serial number. Could you please contact me at support AT literatureandlatte DOT com and include your user name and serial number in the e-mail? I’ll check it out and get you up and running again. Apologies for the inconvenience.

All the best,
Keith
