Why won't Java 7 51 work? It keeps crashing?

[Stacey]

Firstly I would advise you to check if java is installed, go to http://www.java.com/en/download/installed.jsp for the Java Test page
Then you want to open a blank tab in Chrome type the following:
chrome://plugins/
A list of installed plug-ins will be displayed. Check to see if Java is enabled.
(Will show a disable link if it is enabled.)

If that doesn't work you could try using internet explorer.
Load it up, then click the tools menu and select manage add-ons and see if java is enabled

If this doesn't amount to anything it may be worth downloading/updating and running a scan with spybot search and destroy and maybe your anti-vuris software providing it is up to date, just to check if you have any bugs on your computer.
I hope this healps
