Thank you so much for all of your help! The error I had reported was
indeed when opening the application directly from the Downloads folder.
When I had copied it into the applications folder and opened it from
there, it still crashed, albeit with a different error, so I figured
that when reporting this problem I'd focus only on the first issue. But
Maxim's advice of opening it through Launchpad instead of directly from
the Applications folder seems to have done the trick, and now it loads
up fine. Really can't thank you enough, I am so grateful for your help!

Although I'm not sure if that can cause for the problem you have, try installing VMD into 'Applications' folder first and then launch it from a 'Launchpad' so that 'Security Center' asks you for a permission to start it. I have just upgraded to 10.9.3 and VMD runs without any troubles.
