I have tried all the tabs and still nothing. The data is in applications/Fxpansion along with the guru app. I have just realised that none of them work, not just CODB. All the data is there and the wav's can be played. I even tried re navigating to the data but when i click on a hit it is empty. I'm having similar problems with Geist, the only difference being there are no data folders appearing within the app

I would recommend that you move the data folder from your Applications folder. It's never good to keep data in there. Move it to your Documents folder or something (just make sure you don't move the App).
After you've done that, make sure you update the Data Path in Options to the correct path.
