Update:
Not going to work ; it isn't GameGuard, but something just as bad - 'HackShield'
http://en.wikipedia.org/wiki/Hackshield
Took some time to find it ... turns out the game installs fine, but the last part
of the installation .. when you start the actual game client for the first time,
the patching process started then doesn't really patch the game in the regular
sense -- it downloads and installs the Hackshield stuff... (had me confused for a
bit as I kept finding an empty 'HShield' directory after initial install, and I
thought they'd done away with it ... not so when I discovered what the 'patch' did =)
..it goes on to make a complete mess of the registry as well, which leaves you with
a bottle that you can't install anything else into... (wild!) ...took several new
bottle make-ups before I got all the dependencies tracked... horrible thing it is...

That's the winebug associated with this issue, and it would appear unresolved to this
day. I'll ask a Ninja tomorrow if we have a HackShield bug already in the bugtracker
here, and if so, I'll hoist a wishlist bug against it & this app. If that happens, and
you want this problem looked at, you will still need submit a ticket on the issue yourself
(yourselves =) to voice your desire to have this looked at, but from what I've read, this
HackShield system is pretty much a kind of 'rootkit', and as such isn't going to work
'anytime soon' me thinks ....
....wish I had better news, but, you can now stop wasting time with this one ; it's
not going to be working for some time to come yet imho.. ;-/
