How can this be solved? Thank you
It's not much information. Which version do you use(universal client, Windows, Linux, Mac?
Have you tried the previous nano version with the same result ?
Test it with the universal client 2-2-0.
This message appears when you try to load the same wallet file over and over again. Maybe your nano wallet have some old wallet files in the local cache.
Important - make a backup and save your priv.Keys etc..
Look at the lower right corner, there's a wastebasket. You use it at your own risk.
I backed up and used the red dustbin button to clear local storage, but when I loaded in another wallet file, the "Select wallet" option only gave me an option to login to the same wallet in local storage which I just purged with the red bin button. How can I access the other wallets which I have imported?
You should use the " universal client 2.2.0 ".
