Artist to C6 activation code awaiting

Four days ago i have paid for activation code Cubase Artist to Cubase 6.
During that days i have received to my e-mail an invoice and general condtition, but no activation code. And no one told me for how long i must waiting .I wrote from MySteiberg account couple days ago, but no one answered to me, so i asking here in forum.
How long it normaly takes for sending activation code ?

Thank you

Problem was with my yahoo mail box!
Steinberg have sent me code fast, but my box did not receive it, so i had to give to Steinberg hotmail address and code arrived in 1 second!!!

Be careful with yahoo mail box, it is not first time when they do not accept important mails.

Sorry Steinberg!
My best wishes!
