Adobe Premiere Pro CS6 permissions problem

I've purchased membership in the Abobe Creative Cloud. All the apps work except Premiere Pro. When I'm logged into my normal account and try to start the app, I get this message:

Premiere Pro has encountered an error.

[/Volumes/BuildDisk/builds/mightykilt/shared/adobe/MediaCore/ASL/Found ation/Make/Mac/../../Src/DirectoryRegistry.cpp-283]

If I log in as root, the app starts normally.

I've spoken to Adobe tech support. They say it's a permissions problem, not an Adobe problem. I've run Disk Utility and Repair Permissions, but I still cannot use Premiere.

Any advice will be much appreciated.
