You can get V3.04 from
http://rapidshare.com/files/14416405...ch304.exe.html
as was kindly provided by someone on the main forum. I've also cunningly downloaded it, so if you have a problem with that (slightly messy but not too bad) site I can e-mail it to you.
Similarly I can e-mail you the V3.04 exe if you want, but I'm slightly dubious about that - surely the other files must be different too, and that must have some effects? Maybe nothing important though.
Uninspired, similarly I can e-mail you the 3.04 exe if you want. Just send me a PM.
