Authentication error token
I've just downloaded Ubuntu 11.10 and everything was going great. I tried to change the password to match my authentication key, or something of that nature, and now I can't unlock anything. I tried to change the password through the drop root method, because I thought that I might have misspelled it somehow. It didn't work, saying that it was a manipulation error. So, I thought it was the Likewise Open program blocking it. But when I tried to remove it, it said that it could not be parsed. I'm just confused, and wondering if I need to download Ubuntu onto my laptop again and hope for the best?
