Okay, so here are my two questions.
1: I recently ran out of my Gold subscription and went back to my offline profile. I disconnected the Xbox from the ethernet, and my Live profile's avatar looked just the same before I did. Then, when I turned it on today, the Live profile's avatar had several items taken off of it, ones that I had earned from playing a game. I went to put them back on but a ! symbol was there over where their picture should have been. I went into the Hard Drive, and they were there, no indication of being corrupted or anything, I just couldn't use them. Why is this?
2: I re-downloaded some DLC for a game that I had on my previous Xbox. The DLC was shared just fine between Live and offline profiles. Now, though, on my current box, only my Live profile has it and my offline one, which previously had access to it just fine, now does not. Why is this?
