At my current high school, there's a wireless network available for us students to use. Using the school's proxy server I can surf and mail on my X50v but msn messenger was always complaining about the proxy settings and refused to work. So I looked for updates and installed one from the microsoft site... Stupid because I forgot I had WM 2003 SE on my PDA and the update was for WM 2003

I removed the upgrade and now messenger is dead on my machine When I tap the icon, nothing happens.
Any way to reinstall messenger without having to reinstall the entire OS again?

[UPDATE]
I just figured out that reinstalling the update could bring messenger back to life and.. it did Problem solved!
