when in the client, look to the top left where it shows your address.. does it still show "primary" below the address? if so click that address and a drop down should appear with a new address that does not say "primary". that should be the account you have nem in.
nope- it says 'primary' but when I click on that, the same appears below that: same account number with 'primary' in blue again ...
did you create a wallet with a password that was your private key? Or did you do the [Add Existing Account] from the drop-down cog and enter your private key in there?
I created a wallet with what should be my privkey- I wonder a bit about this 64digit hex- format...
wasn't the process like that in the testNEM I entered a random password and then in the testNEM went on 'create real account'
and got the acct number an the privkey there?!?! because I am sure that I never entered a privkey myself - except for the testNEM one...
uhhmmm...
Maybe I misunderstood you.
This is what I did for entering my private key.
1.) Create New Wallet
2.) After log-in to that wallet go to the drop-down arrow and click [Add an Existing Account]
3.) Enter the required info, "Account's Private Key", "Label", and the "Wallet's Password" then press [Add].
4.) It should load a new account that has your XEM within it. If not then click your address and see if it shows 2 Addresses. Your "Primary" one and the Address you created using your private key.
Just for reference my private key contained a bunch of numbers 0-9, and letters a-f
If you did the above and its not showing try see if you switched up private and public key maybe?
