Did you ever get Fallout 3 running? If not, this thread (http://steamcommunity.com/app/22370/discussions/0/828937546147175081/) has what you need. All you will probably need to do is 'update Games for Windows Live' in step 1 and then make the changes listed in step 4. If you are interested in the Unofficial patch listed in Step 6, there may be a way for me to get you the file without you having to register to download it. Once you are through Fallout 3, I may have a copy of Fallout New Vegas to send. ;)
