Ummm... no offense pal, but why the hell would you have had only ONE saved game until that point? <img src="/ubbthreads/images/graemlins/confused.gif" alt="" /> You literally didn't have anything besides your Quick Save? That's never a good idea in a computer game, regardless of the specific game...
I haven't run into the issue myself, but I'm sure somebody can explain why (or how) it happened to you.
