Cannot map message button for messages!

I had the Palm Messaging App installed on my IP 830w and I recently uninstalled it. Now that I've done that, the option to map the message hard key for messaging is gone! It is no longer on the list of options in the button app. Please help!

don't know about the your samsung but install the app and copy the app.exe and paste it in windows/startmenu/programs
it should show up in your buttons settings menu now
