I'm still having the same issue as you, navykat88, and my import folder is in the same location as yours. On the patch notes for 2/6 it says that the folder should be in Program Files/Maxis/The Sims/User Data/Import but that's not where mine is. I don't even have a Maxis folder.
The game is finding the fam files in Program Files/EA Games/The Sims Legacy/User Data/Import but there is an error when trying to import. I have not experienced any crashes though. I wonder if the old files are just not compatible with this updated version?
