Automate unDRM problem: can't find IndivBox.key file

Hello

I used Virtual PC and i did a clean installation of WinXP. I turned off automatic updates, then i installed Media Player 10.00.00.3646 and i tried to play a WMV file with DRM protection in order for the player to do the security upgrade. After that i did the upgrade from Microsoft's site (http://services.wmdrm.windowsmedia.com/indivSite) but after all these steps Automate unDRM doesn't work! The player still wants to connect to the internet and download the license. The strange thing is that after this procedure i can't find anywhere the IndivBox.key file! There is no DRM folder into C:\Documents and Settings\All Users . I even do a search for the file including hidden files and subfolders but with no luck. The only thing that i have found is a License Backup folder in My Music with the files drmv2lic.bak , drmv1lic.bak and drmv1key.bak . Could you please help? I really need to unDRM some files. Thanks
