FOUND THE SOLUTION! I just spend two hours on the phone with T-Mobile and blackberry support. This is how you fix it.

I removed the entire Roxio folder but you can just do the manager folder...


1. Close all open applications, especially Roxio applications. if the device manager is set to open on startup disable it. (right click on the BB device Manager next to the clock and uncheck the box at the bottom.) Restart your computer.

2. DO NOT OPEN THE DEVICE MANAGER.

3. Open 'my computer'

4. Double click on the 'C:' drive and browse to 'C:\Documents and Settings\USERNAME\Application Data\Roxio' where 'USERNAME' is the name of the user you are currently logged in as. (if you don’t see the folder it is either hidden or you are using redirects) you can look up how to unhide files and folders someplace else. And your sys admin will know where the redirects are going if you are on a business network.

5. Right click on the 'MediaManager' folder and choose rename

6. Call the folder 'MediaManager.old'

7. Now try launching the Media Manager

worked perfectly for me.
