Troubles with brand new install of RDi-SOA 7.5

I have been waiting for the media for Rdi-SOA for some time now, so I
could start learning EGL in the newest release of RBD. I finally
received media, built a repository of all components, and installed the
product. Before I launched, I installed updates, so that my product
includes:

Installed Packages and Fixes
IBM(r) Rational(r) Developer for i 7.5.0.2
IBM(r) Rational(r) Business Developer 7.5.1
IBM(r) Rational(r) HATS 7.5.0
IBM(r) WebSphere(r) Application Server Version 6.1 Test Environment
6.1.0.21

I launched RDi, creating a new workspace. Everything seems ok....

Welcome page offers a link to a cheat-sheet called "Create an EGL Hello
World Web Application"

On the "New EGL Project" dialog, I enter a project name, and then select
Web Project. Next...
Select the server runtime (WAS 6.1), enable "Create new build
descriptor". Finish...
A progress bar displays, then an error dialog pops: Failed while
installing Dynamic Web Module 2.4
A second dialog pops up immediately, requesting to run the Rational
Desktop Migration.
If I run the migration wizard, I eventually get to a screen that reports
an undefined server runtime. The new server runtime dropdown lists the
environment that I had originally targeted, so I select it again... Get
a bunch of warnings in the Migration Results panel, then a dialog saying
validation completed with some errors. Reviewing the "Problems" view, I
see this message: "This project needs to migrate WTP metadata"
The question for me is why the project migration wizard would run on a
brand new never-used-before workspace.

Any clues how to get this thing up and running?
