Freezes on Splash Screen

Photoshop CS freezes on splash screen. I have been using this since CS first came out without problems. Now it will not go beyond the screen and locks up with 100% CPU usage. Athlon Barton 2500 w/2G Corsair Ram, 2 - 160G Seagate 7200 HD's configured with Raid +1. All other programs work normally...just PSCS :confused:

Should add that I have uninstalled CS and reinstalled it. I have also removed each 1G stick of Ram and tried it...then swaped the other stick...still no joy.


Any help is appreciated,
Dave

Thanks to those that took a peek, but I have resolved my problem. For those that haven't run into this prior...you need to reinstall using the "non recommended" installation. The one where it will have to be reactivated and deletes user preferences :eek: After the fact I found that I should have saved my user preferences and copied to another location...just in case.

Hope this helps someone,

Dave

I imagine that deleting/moving the Photoshop preferences file and restarting Photoshop would have forced Photoshop to recreate the default preference file without having to reinstall Photoshop.

Had the lockup issue on a friend's Mac, and the above process resolved it.
