hello, I have a little problem.
I want to open my wallet but it says:
"Oops! ERROR 121
The address book file does not exist."
But I'm sure that I registered correctly back in december...
Any tips? Thank you!!
Hi, please create a new wallet and import your private key (it holds your XEM) via "Add Existing Account".
