Delete Vendor.xml on Win 7

For you that has ever been got a problem with reloading the Operating System on your OS 7 BlackBerry, Please try this , I just know that vendor.xml not only on c: program files/common files/research in motion/apploader, it also has another .Xml on c: users/appdata/roaming/research in motion/blackberry desktop.

Try to delete this two .Xml extension if you still cannot load an OS into your BlackBerry with OS 7 before buying a new One. Hope it solves the problem.
