Don't use DM to load the update. Once you download the update, you need to install it to your computer. Double click the icon of the download (I always save the download to my desktop) and follow the install instructions. Once installed, click on "computer">C drive>program files>research in motion>apploader. Once in apploader file, scroll down and delete the vendor.xml file. plug in you phone. Then go to the Loader icon in the apploader file and click it. Follow the prompts. You do not need to wipe your device since apploader does it for you. You do not need to back up your files since apploader does it for you. Simple.
