    I don't think there will be a visual serial here... serial fishing will not work... We must do some calculations...

    :0041332C DC3580104000 fdiv qword ptr [00401080] < divide by 6780496716

    :00413338 DD1D44404100 fstp qword ptr [00414044] < store at 414044

    9.8 is dependent on our input
    ---------------------------

    :0041333E E8A1DEFEFF Call 004011E4 < get length of code eg 1
    :00413343 69C04D010000 imul eax, 0000014D < length of code X 333 = 333
    :00413349 898560FFFFFF mov dword ptr [ebp+00A0], eax < store at ebp+00A0
    :0041334F DB8560FFFFFF fild dword ptr [ebp+00A0] < 333 pushed to ST(0)
    :00413355 DC3560104000 fdiv qword ptr [00401060] < divide by 8
    :0041335B DC3568104000 fdiv qword ptr [00401068] < divide by 60
    :00413361 DC2570104000 fsub qword ptr [00401070] < -(-2) = +2
    :00413367 DC2578104000 fsub qword ptr [00401078] < -0.325
    :0041336D DC2590104000 fsub qword ptr [00401090] < -0.8375
    :00413373 DD1D4C404100 fstp qword ptr [0041404C] < store at 41404C

    answer in 41404C is dependent on the length...

    :00413379 DD0544404100 fld qword ptr [00414044] < load value from above to ST(0)
    :0041337F DC1D98104000 fcomp qword ptr [00401098] < compare to 72

    So, we must find a serial/code that will fit both part 1 and 2 for it to be correct...
    Sounds like if we can find one, we will be able to generate a KeyGen for it. 8P

    bye!
