download fail

I am able to run my kit in Windows XP but not in ME
In Windows ME The drivers install for Luminary board A and B but not for the Virtual COM port.

However when I download the drivers from the FTDI site
instead of the one provided with the kit they install two COM Ports

When I try to download the hex file the IDE gives me an error saying " Flash Download failed Target DLL has been cancelled "


Any ideas !
