Unable to start Draftsight on mac

I've been struggling for a while now to get Draftsight Beta V1R3.1 to work on my boss' Macbook Air (OSX  10.7.5, 1.7 GHz Intel Core i5, 4 GB RAM).

Everytime I start the program, it hangs with a box entitled "Command Line" near the bottom of the screen.  I've attached the crash report.

I have removed the program, re-downloaded it, repaired the disk permissions & rebooted, many, many times.  Always the same error.

Today I did manage to get the program to startup by creating a different user.  Unfortunately, this doesn't really solve my problem as it's not practical to have another user just for this program.  When I started successfully as a different user I received the verification e-mail message, which has never appreared on the original user.

I'm at my wits end.  Can anyone please help?

Thanks
