Can't connect to WMDC using Windows 7

[CupofDice]

I don't know if this was a previous problem with Vista since it was weeks before I last connected my phone to my pc using vista. Anyway I can't connect my Diamond to my pc running Windows 7. I have tried unticking the 'enable advanced' option in usb to pc, and i changed the name of the device to My_Diamond (previously was Diamond). Still won't connect. It did connect a few days ago after multiple reinstalls of WMDC and restarts of 7. So, anyone know what the problem is? PS- I know there is a thread here, but I can't find it anymore.
