Greetings Andy:I think you're correct. SP2 is probably the root of your troubles.
The first thing I would try is wiping out the ActiveX control in case that was corrupted in the download.
To do this:
From IE Tools/Internet Options: General Tab: Temporary Internet files box: Settings...: View Objects... button, delete VL8X Control, then try the Flight Terminal again.
The system will download a fresh copy of the Launcher.
> Browsing through IE Tools/Internet Options/Advanced/
> Browsing section.
> The "Enable Instal on demand (IE)" is UN-checked
> and "Enable Instal on demand (Other) is Checked.
That's what mine says, so I think you're OK there.
Let us know what happens.
Ben
