Well it should only take in total up to 7 days in a perfect environment, we had the same problem at our school (spilt site two seperate domains) the first stage went fine installed the aps on the first server but whilst waiting for RM to authorise us, i decided to install it on the second site only to find out it needed a seperate serial key, then after 4 weeks waiting & numerous phone calls we finally recieved the second serial key, but after that it was installed on both sites within 5 days (inc. school key confirmation)

Only problem i've come across is when logging into the admin cp, IE 5 & 6 automatically returns to the log on screen < wierd but only happens on one site, i have a feeling it has something to do with the current GP settings.

@suesmate
Do you also have seperate curricullum & admins domains??
