Well, it finally installed through ORBX with all dark screens still. I don't have the tab "Installation" in my Addon manager. I guess it's because all of the installs are handled by ORBX. This is annoying. I'm sure if I were to buy another copy through Simmarket it would look fine like yours.
I uninstalled it through ORBX and now it won't install properly. ORBX Central just hangs on the installation on the "finalizing and cleaning up" part. I don't know what's going on.
