Hi Giridhar,
1. Open the RUN command. If you do not have the "Run" option on their menu, there is a 'hot-key' command you can use (WINKEY+R). Press the windows key then the "R" button.
2. In the "Run" bar, have them type in one of these 2 strings:
Windows Vista: c:\Users\%username%\AppData\Local\Microsoft\MAF\Localstore
Windows XP: c:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\MAF\Localstore
3. Delete the Contents only of this folder.
When the you launch the desktop tool, this will rebuild all of your localstore, you will also have to download you entire account, this is similar to reformatting.
