ssh not working (and neither does sftp etc.)

I started with patchstick on AppleTV and all is well. I got boxee/xbmc and ssh. I then switch to atv flash, however, after I installed it, I can't have ssh (or sftp) anymore. I got connection refused all the time. I checked the setting (in nitoTV? don't remember), but SSH is "off" and it's grey. So I can't enable it. Anyone has an idea?
