N800 - OS2008

Another problem...

My browser will not open. It says Web-Loading - then flashes a box that says Updating and then goes back to the home screen. This is the second time I've had this problem - had to reflash last time to get it to work. Would like to know what is causing this and how to fix without reflashing. I do hot have any apps installed other than what comes with the base OS2008 install.
