Java Installation and Trouble Shooting Tips
Over the last few months there has been considerable concerns with Oracle's latest updates of their java and concerns over security issues. We can assure you that the current version as of this article (Java 7 Update 45) is safe to use and we highly recommend that you always keep up to date with the latest java. To get java go to Oracle's site for the latest.
If you still seem to have issues after installing the latest java we offer the following:
Make sure you do not have any older java remaining in your computers system. Go to your control panel and uninstall all current and previous versions of java including JavaFX if it exists.
After removing all java from your system then go to http://java.com/getjava for the latest version.
Make sure that your browser security settings are not set too high. Generally, medium is sufficient for Internet Explorer. Additionally, make sure your antivirus software isn't blocking the chat or your java software.
If you are using a MAC we suggest that you go to http://sourceforge.net/projects/javaplugin/
Sometimes MAC computers will download an automatic update to the Mac OSX software. This has been hitting Mac users since mid May of 2012. From our understanding the update has effected the default security settings for Java which is installed on your Mac. When these updates went through, Java was apparently unchecked by default in the OSX security panel.
If you go into your security control panel on your Mac and ensure the box for Java is checked this should resolve the issue. For more assistance on your Mac security panel and Java related issues, Please visit the apple support web site. http://support.apple.com/kb/HT5268
We hope the above information helps you with any problems you might be having.
