I tried to update to the new OS v4.5 using Desktop manager v4.6, in the process of updating the OS my phone showed a 507 error, and everything locked up at that point in the process. From that point I could not connect to the phone through Desktop Manager. I closed all apps, removed battery from phone, and uninstalled all software. Reloaded all software, and now I'm still unable to connect to the phone through Desktop manager? I was going to try the OS update, but it won't allow me to do that, because I cannot connect to the phone through Desktop Manager.

Notes:
Running Vista Ultimate on Desktop
Desktop Manager v4.6

PLEASE HELP!
