SPAMFighter on Vista x64

I've been using the SPAMFighter program with Outlook Express on my XP
machine for several months and have found it to be excellent. I decided to
purchase a second license for use with my Vista x64 machine and stupidly did
not notice that the program isn't supported for a 64-bit OS.

I've apparently wasted $25 on a program I can't use, but before I call it a
complete loss I was wondering if anyone had any ideas on how to make the
program work on Vista x64 and Windows Mail. The program installs fine, it
just does not appear integrated with Windows Mail.

Thanks in advance.
