- A quick fix that usually works is to disconnect your Internet so that DM cannot communicate with online for updates. This will force DM to look for the update on your PC.
- If the above fix does not work, then you need to launch App Loader by itself. You will need to close DM completely because sometimes it will stay running in background and will prevent App Loader from detecting the update as well. You can find App Loader in the same location the vendor.xml file is found.
Also, make sure (especially on laptops or netbooks!) that USB power save is turned off! This can NUKE your blackberry!
