Okay, disconnect your BB, shut down the Desktop Manager, go in to Windows Task Manager and make sure any process related to either BB or RIM is ended. You may see one process for each, so make sure you shut down the process. Now try it again.
Also, when you installed the OS on your computer, did you remove the vendor.xml file before attempting the upgrade?
