NOTE: This tutorial is not totally for newbies so i excpect that u know
1.how to use w32dasm
2.how to use hview (change,search,etc...)
3.Assembly


move ur system date and open the program expired right ??? Good

the try is disabled

these kinda programs do the check of the time time every time the program starts

disassemble the program

from menu click on debug ---->load process--->load and u should be here


//******************** Program Entry Point ********
:0048AB30 55                      push ebp
:0048AB31 8BEC                    mov ebp, esp
:0048AB33 83C4F4                  add esp, FFFFFFF4
:0048AB36 B858A84800              mov eax, 0048A858
:0048AB3B E830ADF7FF              call 00405870



click on the step over till u get here

:0048AB4F E864F9FFFF              call 0048A4B8 ----->calls the nag in the call it does the time trail and 
:0048AB54 84C0                    test al, al         ; it choses expired of good
:0048AB56 7471                    je 0048ABC9         ;the try button


when u get here the nag comes up and gives u the option to try 

click step over and when u get here 


:0048ABBD A100C14800              mov eax, dword ptr [0048C100]
:0048ABC2 8B00                    mov eax, dword ptr [eax]
:0048ABC4 E8078BFAFF              call 004336D0    **** the real program starts.....


so all u have to do is change the call to jmp and change where its going
change call 0048A4B8  to  jmp 0048AB54


:0048AB4F E864F9FFFF              call 0048A4B8  --------->it will jmp to the next line
:*0048AB54* 84C0                  test al, al


this way it jmp and comtinues like it already check and u click on the try button
which mean it check the date and ur OK
