V10.2 & Internet Explorer v9 Issue

Question

I installed Internet Explorer 9 and then received notice that Flash was outdated. I upgraded Flash to current version. Pandora, now, doesn't work. Their website suggests that the problem may be with Flash. I went to the Global Storage Settings panel at Adobe and found that page to have the same problem as Pandora. The Panel itself does not appear (there is simply white space where it should be) and there are no icons on the left of the page.
What can I do to get this back to "normal"? (Is there a way to reinstall the earlier version of Flash perhaps?)

Answer 1

(Things turned very ugly. I cannot post a Reply on the Vista machine -- says I cannot post a blank message. Anyway, here is what I tried to post>)
Okay, I reinstalled the nVidia driver (from their website - v266.58). No joy.
Developed a new issue -- now cannot login to Pandora on this computer; I can on the other computers.
Anyway, I turned off the Active-X filtering and again no joy. Turned it back on with no change.

The first URL does not allow me to see (or use) the Flash box -- there is a blank white space as earlier observed.
The second URL shows me a graphic (where the Flash Box should appear) that tells me I need to have "Flash to play." And a button to download and install.
I have not contacted Pandora but it does seem to work properly with Flash v10 on the Windows XP machine.
Wait!
Now I cannot play YouTube videos... says I need to install Flash.
I uninstalled Flash rebooted. Install Flash but still cannot use YouTube and both Control Panels say I have to install Flash... I used the button there but no change.
