FJ Software

The first one I connected was my SE W980, and then when I turned that off and tried connecting my W810, the error that my phone could not be detected came out. I connected both through Bluetooth.

I did most of the options (restarting my laptop, taking out my phone battery for 2 mins, etc), but I still can't seem to connect it. I'm using MPE 1.8 if that helps any.

You have to initiate first the service "Serial connection" in your Bluetooth-Software

erm.. How do you do that from my Sony Ericsson phone, exactly?

You have to do it in the Bluetooth-Software (on PC)
