OS X troubles

[Johan K]

Write this at the terminal and post the result.

ls

ls Dominons3.app/Contents/Resources/

Edit: oops, didn't see that you had already posted that.

Here are a few things I would try:

Run Software Update and update any OS items that might need updating.

Turn off any virus or spyware software you might have running in the background.

Uninstall and reinstall Dominions 3.

Hope one of these helps
