Ok, so are we trying to solve the Roxio issue or to get the password requirement off you BB?
If you want to get your password off you need to see the link I provided on Removing IT Policy. You will need to follow the steps exactly.
I got in touch with my contact at RIM today and asked about this whole IT policy issue being permanently being installed on the device initially input. He told me, they are working on a fix for the individual so that IT policies can be removed without having to install a blank one.
I would look for programs available Over the Air (OTA) that way you just hit the link with you BB browser and say download and it will isntall. If you want to use the PC, just dump the program on your desktop and use the Desktop Manager to load it (make sure you get programs that are compatible with your model). To load hit application loader (while the phone is connected via USB) and it should find them to load.
