I did reboot. Going to try it in a virtual machine with Win Xp Home to see if it has something to do with it. Then I will install NOD32 and check if it crashes the VM. EDIT: After a couple of tests, without NOD32 and without Zonealarm installed, and rebooting 1 or 2 times, it works. I guess a quick workaround would be to use it in a VM, but not everybody can afford to use their ram like that. So if you want to be able to use it right now, I would say uninstall your anti-virus and firewall, but who wants to do that...
