problem with user profile after reseting

hi
i used UM for acconuting in my office.
I limit my users in 3 limitition mode:
1- unlimite
2- 3h , 300M (transfer) for a day
3- only 500M (transfer) for a day

I used script for reset user accounting end of the day (fo example 00:00:01)
if a user used 3h today his account is disable until tomorrow that script will reset his account.
but there is a problem when user account become reset his profile will become unknown.
for other user that their limitation are not finish. their profile is true.
is it a bug in UM or my config is mistake?
