sorry first i have not understand
now i have copy all the entire text (starting with "{ guid" and ending with "}" in Import Wallet section but say incorect password - so this cant be used
i need somehow to import the private key first
You need the password of the wallet. That wallet is encrypted it cannot be imported in blockchain.info if you don't know the password.
I think crazy-pilot is partly right.
The wallet isn't encrypted with a main password, but it is still encrypted with the second password.
In order to import the wallet, it looks like you'll need to:
1. Add a second password to the new blockchain.info account, this second password must match the second password of the wallet you're trying to import.
2. Import the wallet as described above.
