Yes - I got my download serial number sent to my email along with the others that I ordered less than 24 hours later.
That was a few days ago now.
I'll bet they're still quite busy, but it wouldn't hurt to shoot them a note.
Also, check your email spam folders.
Sometimes that happens.
Edit: Oops! I just noticed
'Plugin Discounts', and not 'Audio Deluxe' where I got mine. Sorry.
