So, in 2010, i bought Fallout 3 GOTY Edition for Xbox 360, and installed all 5 expansion packs from the accompanying disc, which are all still on my HDD. I played it very often, all expansions worked wonderfully, but I then made the mistake of loaning it to a soulless monster who decided to keep it. I recently replaced my Fallout 3 disc for free, but it's not GOTY edition. So far, I understand that I need not be hooked to Xbox Live, and as long as i have the expansion packs installed, they should play via my standard copy of Fallout 3. Here's the catch; They're Not. No messages popping up about discovering any of the sites or signals from any expansion pack, and all my equipment from them is also gone. What am I overlooking or doing wrong? Feel free to give me even the most arbitrary or stupid answers, I probably deserve it.
