I have this in the upgrade thread but I'm posting this here to get noticed. I d/l the latest OS, installed according the the instructions on the PC. I started DM, selected options and then a popup wtih USB-(and my PIN) then it asks for a password. I don't have on on the device so I click ok and away it went, but it went with connecting with device and never got any further. It went all through the timer bar and said no device connected. I retried with no success.
I am having the same problem. White screen with the 561 error. I try to connect and my blackberry Device Manager recognizes my pin#, but my blackberry desktop manager does not ever show as though I am connected when I try to reload my os.
