Cannot turn IsApproved False

[Cirene]

Here's my code:

Dim usr As MembershipUser =
Membership.GetUser(CType(CType(fvPosterInfo.FindControl("UserNameLabel"),
Label).Text, String))
usr.IsApproved = False

After I set usr.IsApproved it takes ok, but when I check the
aspnet_Membership table the IsApproved is still True! Am I doing this
right????

FYI: i had to do this...

Membership.UpdateUser(usr)
