Game saves from older version?

[Sunny3]

Hey,
I played bioshock on my laptop some time ago, and I experianced a game destroying glitch. The one where you have to get a key from a safe, and there isn't a key there, so you could not advance to the next stage. So I just binned the old copy I had (it was only £5 and didnt have the manual, so I knew something would go wrong eventually, haha)

But I saved my save in my documents, hoping I could continue from where I left off when I bought the game on steam. Would this work? Like the key being in the safe now from the older unpatched cd copy I had, to the downloaded one that's currently downloading?

Thanks in advance!
