I have just signed up for the PE version.  My personal space was created and I am able to logon to the website.  I just started to go through the introduction tutorials and it said I should download the development environment, which I have done.   It installed a version 8 and 9 of service studio.  I assume I want to use 9.

When I launch service studio 9, i want me to connect to an environment with localhost being the default.  How do I get past this step?

I also noticed that some of the tutorials from the website launch service studio 8.  This version does not seem to have the same environment connection issue.

Should I be using version 9 at all or is 8 a better place for me to be?
