use the proxycap which has CORE version, you can google it, you just have to install it the 1st time, reboot, then use the keygen by CORE, paste the code and the machine name, and when you get registration failed, open your registry and look for MMTPROVIDER then delete the "key"... then go to the proxycap at system tray then rightclick and go to HELP>>and hit ABOUT proxycap, now if you see your machine name, you are registered. Next time you reboot again, you might need to do it again, but its worth it.
