Rescuetime doesn't start up on Powerbook G4

Hi fellas:

I installed RT on my Powerbook G4. However RT flatly refuses to boot.

EnvDetails:
Powerbook G4 1.5 GHz
RT 2.1.0.657

I dug up following line from console logs

9/30/09 Wednesday, September 30, 2009 10:29:08 AM com.apple.launchd[71] ([0x0-0x86086].com.rescuetime.RescueTime[1404]) Exited: Killed

There is no ~/Lib/AppSupport/RT dir and I have enabled assistive technologies
Any idea what's going on?

Thanks
Manu
