I recently defragged my primary hard drive. Don't know if it's just coincidence or not, but ever since then the application icons on the PortableApps.com Menu will not display. I have tried refreshing the app icons multiple times to no avail. I have tried ejecting and reinserting the thumb drive, no help. How can I get the app icons to display again? I'm on the verge of formatting the thumb drive and re-installing everything.
