Program crashes after splash screen

When I try to run Draftsight,  I can't get past the splash screen and I get the following error:

 "?DraftSight.exe has encountered a problem and needs to close. We are sorry for the inconvenience."

 Both machines I've tried this on are running XP pro SP3 and using ATI graphics hardware. Could it be linked to a particular graphics card driver? Any ideas on the cause?

 Here are the machine specs:

Windows XP Pro SP3

Intel Q6600 Quad Core Processor

2GB RAM DDR2

ATI Radeon HD 2600 XT (512MB RAM)

320GB HD with 50% Free space
