4. go to C://Program Files/Common Files/Research In Motion/Apploader
5. Delete the file "Vendor.xml"
6. Double-click on the file loader.exe

Upgrade OS once only. Disregard any notice for OS upgrade as it maybe incompatible with your unit.
Do not upgrade apps like fb, twitter, ym, or any other IMs. Do not upgrade BBM.
Upgrade only BB Protect and BB Appworld.
