OK, I can answer my own question and hope it may help someone else. Install Connect on new pc, initialise the hard disc on the player, connect player and let them set up their partnership. Close Connect player and copy the library folder from \documents and settings\all users\application data\sony corporation\connect player and then past it into the same location on the new pc overwriting the existing file. Shut pc down and restart, then open connect player and attach walkman, the only files not copied over were the “free” download from Connect Store so I made an audio CD of it and re-ripped it
