Since it is compiled with Borland C++ Builder (u can check that with PEiD), open it in DeDe. Then, in the 'Procedures' tab,click on 'TFormUnReg' and double click on the 'ButtonOKClick'(this is the button u click when the timer is over.You can verify it in the 'Forms' tab).
The code there is something like this:
Code:

* Reference to field TFormUnReg.OFFS_0300
|
0043013C   83B80003000000         cmp     dword ptr [eax+$0300], +$00
00430143   750A                   jnz     0043014F

* Reference to field TFormUnReg.ModalResult : TModalResult
|
00430145   C7803402000001000000   mov     dword ptr [eax+$0234], $00000001
0043014F   C3                     ret


This code is executed when the buton is clicked...
at 0043013C, it's comparing a value to 0.Probably, this is the value of the seconds left because if this value is 0, the form will close.
There, you can patch the line 00430143 from jnz to jz or nop.That, way the nag will close whenever you click the button Wink

DeDe only shows you where to patch...
If you don't want to use DeDe then you have to find on your own where to patch...
