Desk home not launching- missing com.motorola.dlauncher

[ihf]

I have a non-rooted Droid 2 and the Desk/Home dock. When I first tried it out, it worked as expected--starting the home dock screen when placed in the dock. However, I now find that whenever I dock the droid, the notification bar shows that it is connected to the multimedia dock but it does not start the dock application. I used Astro to browse the /system/apps folder and found the Dock app- clicked on Open App manager and then Launch at which point I get a message saying "Activity not found com.motorola.dlauncher". I don't know if this is why nothing is happening when I dock the Droid but can anyone tell me why this suddenly stopped working and what I can do to get it working again?
