Having a mmc card in the phone and hooking the phone up to a usb port is all I need to do, sorry. I can't see the public folder on the phone, but I can access the the card as a folder.
I guess yours doesn't work like mine.
Btw, as for uninstalling pc-suite, it might leave some crap, so when I say completely you might need to check the registry for entries.
Also, had you added anything new around the time it stopped working?
