Last question; How much time I've got to claim my NEMstake @NXT AE? Deadline?

I have a question as well.

1.) I clicked on Create real account data for the first time to check out the wallet. didnt save anything.
2.) I clicked again to create real account data for the 2nd time. Saved all the details, and used the same details to send my nemstake to the account NXT-97MX-EWKV-CGKX-DA5WH. All went fine.
3.) Now i can't seem to find a way to check that same account that i used to send the nemstake. Then i tried the option, ADD AN EXISTING ACCOUNT, paste the private key, the account number generated was different! Is this supposed to happen?

edit: i think the account created was different because of the the software is still in test mode, i assume.

Don't hate the troll-snakes, they only get more energy from it. Love them and they get confused and go away. 

I use the standalone version without default data-path. No possibility to create a real address. What to do?

I don't know how you managed to keep the alpha wallet as usually that should cause some trouble (like the client dying) but it doesn't matter for redemption if that's what your asking.
You're not supposed to use an address that the client creates for a new wallet account. You're supposed to create a "real account" with the generator as shown in the screenshots.
