google play store - Android Market disappeared! How do I get it back?

Since upgrading to FroYo, the Android Market app has disappeared from my wife's Droid X: it doesn't appear on the home screen or in the Applications list in settings. Is there any way to get it back?

from here I tried http://androidforums.com/droid-x-support-troubleshooting/196653-help-market-place-gone.html

To get the Marked app back, without doing a hard reset.

used ASTRO file manager

1. Opened ASTRO, clicked Up


2. navigate to /system/app


3. Locate Vending.apk


4. push on it to install it, clicked ok etc

Now back on home screen, follow what is suggested about a clean slate ...

1. Settings -> Applications -> Manage Applications


2. Chose All



3. Find Market


4. Push on it and select Clear data


5. go back to main home screen, turn your phone off and back on
