I said "tedious" not "difficult."

There are lots of files to change.
In one pirated release of this game that I saw on a public tracker they have the entire process automated at this point, so it's just a matter of double-clicking something. It's pretty crazy what they come up with. And yeah, I've noticed far more legitimate owners of the game being screwed over by the SecuROM stuff than pirates. Seems the lengths they've went to to discourage piracy (level 15 skillpoint overload, etc) is in fact hurting paying customers instead of the actual intended victims.
Can't really blame the company for trying everything they can to protect the thing they've invested so much time and effort in.
