Have you tried deleting both psa.prf and status.dat files in preferences folder ? If that doesn't help then I would suggest creating a new catalog and see if you can access Organizer preferences there ?
I am having the same problem. I have tried deleting the psa.prf and status.dat - no help. Tried deleting the catalog folder - no help. Tried uninstalling and reinstalling, but all the Preferences commands just result in "loading" and nothing ever happening after that.
Any other suggestions? I am very frustrated with this software, and the fact that Adobe won't support this through live chat, even though this is the first time I've called support, on software that I just received with a new Epson scanner.
After deleting psa.prf and status.dat file, right click the 'PhotoshopElementsOrganizer.exe' and select 'Run as admin'. For detailed steps please refer to steps #1 and #2 of Solution#1 as mentioned on blog: http://psekb.blogspot.in/2013/03/pse-organizer-is-not-launching.html
If that doesn't work, follow all the steps of solution #1 on same blog.
Andromeda, Thanks for the suggestion, but no dice. The problem is not that PSE/O 9 will not load, it's that the PREFERENCES will not appear, only a "Loading" message. Running as administrator did not make a difference.This is extremely frustrating.
Additional suggestion: Examine C:\windows\twain_32 for old drivers or obsolete printers. Remove all files and if preferences works, add back one by one. This worked for me, but it took buying a copy of PSE 11 to get Adobe to walk me through this solution.
