English Amiga Board - Internet Modem on Windows XP (Looking for 7.1.7.1)

I'm wanting to get on some BBSes on my Amiga 500 using a null modem cable, and I need this software to do so. I'm using a Windows XP laptop with a USB to Serial adapter. The latest version of Internet Modem on BoycoT Software's website does not support XP anymore and does not seem to provide downloads for earlier versions. The email link is also dead. Here's the site, fyi:

Would anyone happen to have version 7.1.7.1 or whatever the latest version that works on XP is? Thanks.
