The crash report.

Your Java is out of date. Please update your Java to the latest version: http://www.java.com/en/download/ . Keep in mind that when using a 32-bit browser on a 64-bit OS the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp .
