Hello, I am newly using Vassal on this laptop, and I have downloaded Vassal 3.2.17 for Mac OS X. Download seems to be successful, and it is moved to my applications. But, when I try to open the program I get the following error:

“VASSAL quit unexpectedly.  
Click Report to see more detailed information and send a report to Apple.”

I should have the right Java version, since I just went to their site to download the latest version.  
My java -version is:

java version “1.6.0\_65”  
Java™ SE Runtime Environment (build 1.6.0\_65-b14-468-11M4609)  
Java HotSpot™ 64-Bit Server VM (build 20.65-b04-468, mixed mode)

I tried uninstalling and installing Vassal 3.2.16 with the same error.  
The laptop has some firewalls since my university moderates it, which sometimes gives me some problems, but never been unable to open a program like this.  
I appreciate any help, thank you!

What was the “more detailed information” this showed you?

VASSAL has no native code on Macs, and this is a crash in native code.  
Therefore, it’s either a bug in your version of Java or in OS X itself.
