Try uninstalling it and reinstalling with a new download. (I know you already updated but it may have corrupted somehow)
1. Download a new driver version. Save it to your desktop but don't install it.
Click to download from Synaptics: Vista 32bit Driver Download (latest version)
2. Go to: >ControlPanel/ProgramsAndFeatures/SynapticsPointingDeviceDriver and uninstall it.
You will have to do a restart and it make take a bit as it finishes uninstalling before completely shutting down and rebooting.
Make sure your mouse pad works after the reboot; if it doesn't, do a reboot again and it should work.
Double click the new download and let it install. You might have to do another reboot after installation.
3. Share the good news.
