JAVA ERROR

[mmfreidin]

Please Help!
I have been unable to launch EGAN due to the following JAVA error.  I am running Windows 7 with the latest JAVA 7.  Any suggestions would be welcome to correct this.

java.lang.NullPointerException

Can you run EGAN without selecting PermuSEED as an option?  PermuSEED uses a local file system cache, which at first guess, your system might not be able to create.  If EGAN launches without PermuSEED, then we can work further to find the root cause.

Best,

Hi Jesse,
Apologies for the delay in responding to your suggestion.  I am able to load EGAN without Permuseed, but only if I use JAVA 6.  The program will not load with Java 7.  In fact, I had to uninstall Java 7 to get EGAN to run.  In addition, processing is quite slow making it somewhat difficult to work with.  I'm still learning, so this is not a huge problem yet.

Suggestions?

Thanks.

Sorry about that - there's a bug with EGAN for Java 7.  I anticipate that this will be fixed soon...
