    Helo,
    itīs late so I wonīt post much here!
    I tried a search for "sorry" in W32Dasm.Using this I got two spots with referring strings. Code looks like: (1)
    .
    .
    call 0040CCC0 Hmmm...
    add esp, 00000008 ( ??? )
    test eax,eax ... this is the deciding test I think
    je 00405D81 jump if ok else you see the sorry screen
    .
    .
    (2)referenced by conditional jump so here I write code bevor the jump
    .
    .
    call 0040CCC0 equal to the first call (memorize and check after taking a little nap)
    add esp, 00000008 ( still ??? )
    test eax,eax ( test )
    jne 0040B9BC jump for bad laydies (difference to jump in (1)
    .
    .
    Strange thing is that je and jne difference. While testing these jumps I found that if I no-oped one at a time I got problems registering. I no-oped both together and I had no problems. So hereīs something strange You should get an error because the je(1) nop-out doesnīt change anything. Iīm also not a friend of the brute (90-)Nop Out so I want to find an other way. Iīll check the call before the test and the code bevor the call. It might be interesting. Of course I also have to search for other useful strings and surrounding code.

    thatīs it for now.
    have a nice day
