There has been a number of emails and basically they keep asking for the e-mail address that was used to set up the wallet.

From their part, there hasn't been any other suggestions how to solve this.

My last response to them (which was on Sunday) was to give them a couple more email addresses to try. The ones I have given are not active but it seems if I can at least give them the address then I have a chance.

If there's a negative response then I have no idea.

Surely, people losing emails addresses after 10 years is a pretty common thing, so there should be another mechanism, as long as all the other security info is correct.
