8.0b is what I’m using too.
Did you get any errors when installing it? Remember to uninstall Aav6cc beta 1 or 2 if you tried that earlier.
Otherwise, could you look up the following in either Explorer or Internet Explorer?
file://%APPDATA%/AAV ColorLab/log.txt
If that doesn’t give you anything, try %APPDATA%\AAV ColorLab\log.txt
Post the text back here please.
