I can try the programs out for you if you want, seeing as they're freeware anyway. You could also try to run it from a terminal and see if there are any error messages being written back - assuming of course you can find a way to see the terminal once the app has crashed.
I notice you're using an ATI graphics card. Do you happen to know what version of their drivers you're using? I have NVidia on both my machines at home, so if it works without crashing, might be a clue.
FYI: If X craps up like that, you can use Ctrl+Alt+Backspace to kill it, and it should return you to your login prompt.
