Lackey crashes immediately upon opening

[redkid43]

I have a MacBook running really old Leoplard (10.5..  I have never had a problem running lackey before, but now, eveytime i start the program or download it from the site, it will immediately crash upon opening.  I dont even get to the first screen.  The icon appears on my dock for about a quarter of a second and then it just crashes.  This is super frustrating and I literally cannot think of anything else wrong with it.  Please help.
