Just my $0.02, but I have doubts that it's a windows problem, or a Road Runner problem.
A problem I have encountered is with Adobe products and their install/remove software. Both Adobe and Symantec (Norton Anti-virus) leave behind a good many things after telling windows to remove the product. It's almost impossible to go "back" a version. I experienced this when trying to install Adobe Acrobat Pro V6, over the top of Adobe Acrobat Reader V7.
The only solution I know is to remove the Adobe (or Symantec product), then using a program (or manually) edit the Windows registry to clean the system of all traces.
If, as I have assumed, the issue is not with folks who have a V9 flash, then install a V8 flash, my apology for wasting bandwidth.
