Sorry for the wait. Things have been crazy here.
I tried it on a computer running Vista (I run XP) and got the same issue. I left it to soak on the injecting screen for about an hour and it never completed. The progress bar never even ticked.
What else can I do?
EDIT: Trying it again on my computer, I finally got it to work! I'm... not sure how, exactly.
EDIT 2: Okay, I've got the save files loaded, but 007 won't load them. I go in to a new mission, get through the cutscene, then back out to the main menu and select Load Mission. Then it gives me an error and says it can't load the saved mission. Argh!
EDIT 3: Okay, call me Captain Observant. My copy of 007 is the Platinum Hits version; I missed this because it doesn't say so on the box, only on the disc itself. How often to we even look at game discs? Anyway, gonna try it with Splinter Cell.
