Registration Number?

Hi, Colin.

There was a long delay with mine and I PMed one of the Cake staff, who looked into it for me. Whilst he was investigating, the number appeared.

How long have you been waiting?

That's a bummer - much longer than I had to wait.
 
I originally PMed Seth Kellogg, not realising that he'd changed job, but he still kindly looked into it.  He suggested PMing Ryan Munnis.
 
Perhaps you could try PMing Ryan.  They should be around soon.
 
Hope you get it sorted soon, I know how frustrating it can be.  I think you'll love X3.  Is the new studio up and running then?

After installing from the DVDs I entered my redemption code at 12:03, Sat 12/10/13 and the registration code appeared via email at 00:27, Sun 13/10/13 (both BST).  X3 appeared in my store a/c at sometime 12/10/13.  As it was a weekend, even allowing for the time difference I assume there was no manual intervention.  They must have as slow system if it takes >12hrs to automatically grind out 16 characters!  But the package ran OK on 'register later' till the code came through.  Nowhere near as frustrating as Cakewalk used to be, when you couldn't run the software at all for days waiting for a serial number after the download.  Note to self: it's worth waiting for the box!
PS.  I still haven't plucked up the courage to edit the keys in the Windows registry to upgrade Dim Pro since X2!    Registry editing just for an upgrade to a product I originally paid for as a standalone!  Most users won't even know what a the Windows registry is - or how terminal it can be to mess with it!  How crap is that!?
 

I had the same problem. Got the registration by email, but it's still not in my account. I think there's something wonky in how it's all tracked when you order the download from somewhere other than the Cakewalk store.
