Web interface Page Cannot Be Found after upgrade from 10250 to 12200

Hi all,
I've just upgraded from build 10250 to 12200 and now have a broken web interface.

Running on Linux and all the server side of things seem to start ok but after login via web browser I get taken to:-

/netflow/jspui/NetworkSnapShot.jsp

Which brings up a Page Not Found error in the web browser.

Any suggestions?

Cheers
