virtualbox.org

Hi you all,
I'm running VB on a debian box, installed the lenny version.
I was installing xp but it crashed down, after killing the VB process it still refuse to start again, also trying with -debug switch it doesn't tell anything.
I already looked for any installed and conf files, deleted them and nothing changes.
any idea?

Do you get any error message? And if you do, what is it? Did you also remove all references to VMs (removed the .VirtualBox folder from your home)?
