assuming you still have the cab files to reinstall, you can just delete the program files folder on your memory card and reinstall.
however a lot of programs will run fine without being reinstalled, go into the program files/your app folder and try run the executable. if it works, then you dont need to reinstall it. Press and hold the file, choose copy, browse to the phone memory/windows/start menu/programs and press and hold, on teh popup choose paste as shortcut, and it will be back in your start menu.
