wine users - Jul 2010 - HTML rendering is currently disabled (Wanna' play GUNZ!)

Okay, I'm a super super-dee-duper newbster. Aaaaand I'm on a MacBook.
Aaaaand I'm running Leopard (10.5.8). So I've used Wine before a loooong
time ago for some things, but nothing big. And now I want to play Gunz (from
ijji.com). I got everything downloaded (the reactor) and then it tells me
something about "Gecko" needing to be installed. I get everything all
installed and check "Launch Ijji Reactor" box on the final page of the
installer. And then it takes a while, and then a white box pops up with
"HTML rendering is currently disabled" written in the middle. I'm
discouraged. So I go do some research, but I just don't know enough to wrap
my head around it. Got any tips?

Okay, so I tried a direct file download (Not with Reactor), and I got the Gunz
downloader. Installed and tried running it, but got an error message:

X Error of failed request:  BadValue (integer parameter out of range for
operation)
  Major opcode of failed request:  129 (Apple-DRI)
  Minor opcode of failed request:  2 ()
  Value in failed request:  0x20004f
  Serial number of failed request:  453
  Current serial number in output stream:  453

THE HELL?!

'Kay it says WineHelper version 1.0b (1.0)

And I got Wine a LOOOONG time ago. I just got a new one just in case, but
uninstalled. I don't know what version, but it's like... x86. Not sure
what that means. And I don't know what virtual desktop is, but would that
help my second problem (my follow-up post)? And I don't know what the AppDB
/ FAQ entries are, haha. I'll go look'em up, though.

Yeah, did, James, thanks. He's actually the first guy I contacted about it.
