Cell DNA Crashes When Opening

I just purchased Cell DNA and when I first started, I could open it and the program worked fine. Now, every time I open it, the program crashes.

I've uninstalled, re-installed several times. Updated my quicktime. Still nothing has worked.

Is there any updates I'm not aware of? Or, is there something else I should try.

Here is some general info about my computer:

Macbook Pro / OSX 10.6.8 / Processor 2.4 GHz Intel Core 2 Duo / Memory 4 GB 1067 MHz DDR3 / 16.7 GB of Hard Drive available.

Thanks
