If you don't feel comfortable opening a ticket for installation support you can also try checking a few additional IIS settings. Usually, the stylesheets do not load if your server's IIS settings are restricting their usage of certain file extensions. (In this case, .ashx) Often times, the installation of cold fusion or other IIS related apps (like Plesk) can add custom settings to your IIS that prevent certain extensions from being accessible by .net apps.
On the file extensions setting page please make sure .ashx has the "Verify that file exists" checkbox unchecked. This would be a good place to start in debugging your install as it seems the handler is not able to load the appropriate stylesheet for the portal. Somehow, your IIS is restricting the use of .ashx files (or handlers)
Thanks! Hope this helps.
