Hi there.
Although it may sound (and probably is ;) an ugly solution,
but:
After installation of SF5 and quick realization that CD-A
isn't going to work, I've created another win installation
on the same machine and installed 4.5+CD-A on it...(CD-R
driver, too) && (Different directories, of course). So, I
can make my edit/create -> save -> reboot to new win
installation -> use your CD-A.
Ugly, I know -- but I like it too much, and, as many of you
are pointing out, money are already spent...
