Handcent not vibrating on Android 2.1 on HTC Hero

I have been trying the whole week to get my Handcent to vibrate again when my phone was set in Vibrating mode. All this happen when I upgraded my HTC Hero that uses OTA to update the firmware.

I have tried to uninstall it and restart the OS and follow by install again. However it never vibrate anymore in vibrating mode when message came in. However when someone called, the phone will vibrate. Is there how it should be? I don't think so.

Anyone facing the same problem and found any solution for this?
