This is probably a question to which the answer is "no", and I am not interested in cracks, hacks, or anything illegal so please don't suggest it.

I purchased a PC copy of Fallout 3 on release, registered it with GFWL, played it, bought all the DLC via GFWL using Microsoft Points, played it some more, then put it to one side to play other things.

I now cannot find my disk - it is around here somewhere, but if you could see my flat you'd understand, the entire place is wall to wall ceiling-height bookcases filled with books/DVDs etc.

I was just wondering whether the fact I had registered it on GFWL would mean that they would have some way I could access a downloadable version, but I can't find any way to do that from within my GFWL account - is it possible and if so how do I do that because I can't find that as an option? I have the key code and registered the game/bought all DLC on my GFWL account.

Or do I just have to write it off as "one of those things", grumble under my breath a bit, and buy the GOTY from Steam before the sale ends??
