Thanks, mjglqw. I wasn't sure what my problem was either, but I seem to have sorted it or, more likely, it seems to have sorted itself!

I hoped the two would just work together.

I received the Nano today. It comes with no useful instructions but the Ledger website told me to download this wallet which I did. And, ever so occasionally, I manage to open it after maybe 20 minutes.

The nano opens with my PIN but then does nothing other than allowing me to choose Yes or No for support.

Can I find out if I have a normally working Nano?

Thanks
