I recovered my gamertag on a friends xbox. Then I got back on mine and played a few games and got a couple hundred acheivement points. All the while, I was not connected to xbox live, but I was signed into my name. The when I reconnected to live through my xbox, I had to re-recover my gamertag. When I did I lost all the achievements I acquired while not on live. I understand I probably can't get them back. My main worry is that most of the achievements I got for fable 3 were given by completing quests throughout the game. So if I wanted to get them again I would have to start over and play through them again. Which I don't feel like doing. I will If I have to, but I would tater not. I have not played fable 3 through live so I'm not familiar with it, but I was wondering if I could join someone elses game and do the quests again through that person. Would it give me the achievements?

Thanks for your help.
