I recently purchased The Cave via the App Store on my Mac (running OSX 10.9.3). The install progressed via the progress bar on the icon, but never got to 100% and stuck there with the progress bar still visible (and I was unable to launch the app). I tried re-boots to clear the issue, but the only thing that worked was to drag the frozen app icon into the trash. Now I can't re-install the app as when I go to the App Store it says 'Installed' under The Cave (obviously still thinks I've got the app installed). Any suggestions on how I can clear this and re-install to try to fix the issue?
