Try putting

T_Log.Enabled = true;

after you've added the Tick method and

T_Log.Enabled = false;

when your process has finished i.e. before

C#

Lbl_Countdown.Text = "";

[EDIT after seeing OP code]

Your problem is that you have 2 tick events registered for the same timer. It is difficult to debug as you have used an anonymous function for the second event.

Do yourself a favour and change your code like this ...move the anonymous function into an explicit one

C#

private void T_Log_Tick_1(object sender, EventArgs e)
{
    Lbl_Countdown.Text = (TimeSpan.FromMinutes(1) - (DateTime.Now - startTime)).ToString("hh\\:mm\\:ss") + @"";
}

and in your Down_Counter function use

T_Log.Tick += T_Log_Tick_1;

Now place a breakpoint on

Lbl_Countdown.Text = "";

Run your program, and when it breaks use F11 to step through ... notice that the next thing that happens is that T_Log_Tick_1 is then executed, changing the text of the label from blank straight back to a time again (00:00:00)

You don't need two tick events. Just code the one
