So I just bought Fallout 3 from my local game store (EB Games) and have tried to install it, but it seems a fair bit is actually missing, I don't have the "read me" document or the manual, so I went ahead and tried to figure out how to install it myself (can't be to hard right?), but when I click on the Steam Setup icon (I do already have a Steam account and Steam downloaded on my computer), I get a notification saying "No AppID configured", what does this mean? and is there a way to get around this? or do I need to get a return? Please help, I love Fallout 3 and I want to be able to replay it on PC.
