How long do we have in order to do this? I might just download a wallet to another computer as I am afraid to lose all my coins if I try to back them up and re do the new wallet download. Do I have at least a few days in order to do this or I must do immediately? I have to arrange some time to do this as my day has been swamped with a lot to do including de-weeding the garden. I hope to try to download a new version tomorrow if that is still possible.
