Problem Restoring a Profile

I recently re-installed XP on my computer, and in the process of
backing up all my information, I simply saved my profile folder in the
AppData path. I did NOT however create a profile for that folder.

Now that I've reinstalled Firefox, I put that folder in it's proper
place and it doesn't recognize it. In fact, when I start Firefox, it
says the program's already running when it really isn't.

My question is how can I restore all of my
settings/bookmarks/extensions inside that profile folder now? I
haven't found anything on the firefox website that has worked thus far.
THANKS!
