Attempting to transfer profile data - Firefox is not importing the data

I had to wipe my system clean and start anew with a new version of Windows. I have my data backed up, including my old Firefox profile. I have followed the instructions for importing the profile data - by copying and pasting from the old profile into the new, but Firefox is not reading my bookmarks, passwords, etc. What am I doing wrong?
