Sorry to hear about your frustrations...
For your specific issues I recommend, if you have not yet done so, getting plugged into the Photoshop and Bridge forums at Adobe.com. Issues on
PS CS3 and Bridge 2.0 are starting to be reported for which some solutions have been identified.
Hope between here at
RP and Adobe.com you get info on how to get you going.
Was this your first install of Photoshop or are you upgrading from a previous install?
