[stunnel-users] Error when executing stunnel 4.06 Windows binaries as service

Hello, I'm trying to run the offical stunnel 4.06 Win32 binaries from stunnel.org as a service, but I get the following error: "The procedure entry point freeaddrinfo could not be located in the dynamic link library WS2_32.DLL" I looked it up a bit and it seems to have something to do with IPv6, but I don't use it.. stunnel 4.05 works fine as a service, and worked without a problem for months now. I'm using Win2k SP4 fully patched. Help? :)
