Blender won't launch anymore!

Hello all:

I recently updraded my G5 Mac to OSX 10.4.5, and now Blender won’t launch.

I receive the following error messages:

Loading USER=Wayne failed: Unable to open

or I receive:

Loading SHELL=/bin/bash failed: Unable to open.

Any idea how to fix this and get it working again?

Thanks!
