yep, sorted now. Got a download of the US version, upgraded my original connect software to eBook Library, logged in to the store with the 505 connected and it recognised it straight away, asked me if I wanted to authorise it.
Copied over the books I needed to
then went and picked up some mobipocket books for myself. this time I've left myself more comprehensove notes as to how to get them on my 500, the note I left myself 6 months ago meant nothing to me
