bacup of original crashes

[handyman156]

i have backed up the origin-al of my lotr-return of the kings,
heres what i done,
installed ok, then when it asked for correct cd, i pasted the no cd crack,
game runs for 5 minuts then when gandalf says its time to battle for middle earth, the error code appears
code 00000005 at 004801f9

has any one any idea if this is some kind of new protection, i read that there is going to be something like this available so it hangs in a specific part of a game to get you hooked,

any ideas or similar problems ?
