Yes there is a message and when you click ok the program stops.

That is not what happens here - at least, I just uninstalled the Photoshop Bridge, deleted the Photoshop path from the Applications tab of preferences, and tried reinstalling the Photoshop Bridge - the error about the missing path popped up, I closed that and the Install Manager remained open so that I could reinstate the path and successfully reinstall the plug-in. Please check your log file after the crash - if you restart DIM there's a link in preferences - and post any messages relating to the crashed session.
