Nokia :: N86 - Phone To PC Connection / Cant Find Model Specific Driver

I am using Windows 7, fully updated with as far as I can tell a fully updated version of the N86. Recently got new firmware, but can't say for sure if this is when the problems started.

The problem I have is I am unable to connect the phone to the PC and get it to work with either Ovi of PC Suite. I have tried re-installing the drivers, but every time I plug it in, all I get is a Windows message installing drivers, and then a message saying S60 handset is installed, and a Windows screen giving me options such as file transfer etc.

If I try and connect in either Ovi or PC Suite, it can see the phone but says it is not in PC suite mode, even though I have selected this option on the phone. I have a feeling that Windows is installing a generic S60 driver, rather than a model specific one, and this is what is causing the problem, but I can't find a model specific driver anywhere.

This phone has been working on this PC before, and I seem to remember it installing 3 or 4 drivers when first connected, but now it only installs an "MTP USB Device" driver. Any help would be appreciated, because at the moment all I can do is transfer files. No backups, no syncs, nothing with either Ovi or PC Suite, the only access I have is through Microsofts own explorer.
