Windows 7 Portable Devices

I am running Windows 7 Ultimate x64 SP1 and my mobile phone, which is running Windows Mobile 6.5 Professional, shows up fine in Windows Explorer as a Portable Device and when I click on it I can see both of its drives, but I can not locate the phone in Directory Opus 10.0.0.0.4137.x64.
How can I use DO 10 to manage files on my phone rather than having to revert to Explorer?
Thanks for your help

Download the latest beta version (link in my sig), or wait for 10.0.1.0 to be released if you don't want to use a beta. That should fix the problem.
