Ok, I've had some trouble with some fies/folders because for some reason, as I deleted by previous ubuntu account my current one with admin privileges doesn't register as the "owner". I've been able to get around this in some cases with chmod but I'm trying to mount the metasploitable VM in VMplayer and it requires that I be the "owner". I've tried chmod, that allowed my to mount it, but now when I try to run it I get an error. How can I fix this and/or make MY account the "owner".
