Installed SP1 with Admin Studio 7.5. Went through the registration to get a
S/N, and I get to the final screen and there is a red block graphic that
states "Serial Number Here" but there is no S/N!

Is this just a lag in SP1's release and macrovision updating there site? I
recall lots of issues with the last version and getting a valid S/N so I
hope this doesn't occur again.
