I registered my found ID with MAC client. Now I use the windows to see if it's indeed registered. And I see the points, which suggests it is.
I used same ID and same brainwallet phrase, but got a different public ID. Exact same input, different public ID. Can someone tell why? Or it is the way is.
No, they should be the same.
The probable reasons:
1. ID IS character sensitive, WHEN you create your key pair. Because the private key is the hash of all you inputed.
2. The order of name, middle name, family name. It's very probable to take it wrong for Asian people. I myself once took it wrong, for example.
Basically, if you can't regenerate your key pair from memory only, you need to make a new pair of keys and redo the registration.
