Good luck finding that support personnel! I don't think that this works on Vista but someone above mentioned uninstalling Quicktime. You could try that.
I do have the same problem with I.E. 7
I also have exactely the same problem and just had the "custom personnel" on the phone for nearly an hour - with no result. The advice was to check out on the forum or to buy an up-grade "of this out dated software"!
Could you solve your problem in the meantime?
Better late than never I guess - in case anyone else finds this old post searching for a solution to this (there are still some of us old legacy software users out there) just search for and download the Adobe stand alone ActiveX V10 Flash player and install it.
