G5 dual 2ghz with MSN software

[cscgal]

My dual 2ghz G5 mac finally arrived today! Ooooh how excited I am! However, I tried installing MSN software. The installation completed fine, but everytime I try to load the program, it automatically exits on me. I tried logging out and restarting. Virtual PC doesn't yet work for the G5, so I'm thinking it's a similar issue with this other piece of Microsoft software. MSN Messenger, which came bundled with the MSN Software, works without a glitch. Any ideas? It's the only piece of software (aside from Virtual PC) I have yet to get working.
