If there's absolutely nothing on the window, it's very likely that there's an error.
As for your current version, either:
1) Ingame run "/script print(PowerAuras.CurrentVersion)". If it's not "5.0.0.O" then it's RC 1.
2) Alternatively, check the Support Triggers category. See the text in
this screenshot that says 'Showing Trigger: <trigger name>'? If that's not there, it's RC 1.
RC 2 can be
downloaded here.
