Safari Crash After Updating to 1.3.1


I can not connect using Safari any longer after I updated today to 1.3.1. The icon jumps for a couple of seconds and then stops. I can not access my Bookmarks. I have an iMAC Flat Panel G4 and my operating system is MAC OS10.3.9. I can still access the internet thorugh Internet Explorer and have a DSL connection.

I need to be led step by step through this -- I am not technically savvy.
