HELP Please - Renaming not working correctly

I have the file rename mask set as %y_%m_%d %P %{num:3}.%e and cam2pc insists on using 02_01_01 as the date.
I still have not gotten around this problem. Can anyone else shed some light on this - do you have the problem? Is there a way around it? Thanks.
