You're welcome :) And glad to learn there are others who've had successful results with Fidelizer!

I must say your case sounds weird - indeed unfortunate. Have you tried uninstalling everything related to Fidelizer, and then re-installed Fidelizer via the 'Download Fidelizer' link at the bottom of their homepage? Or maybe your problem doesn't lie in the download process, but how you access the file you've downloaded?
http://www.windowsxlive.net/fidelizer/ Perhaps others could help here? I'm no expert into this, but I do know the link works on my HTPC and several others I've recommended it to.
