So, tried to do that again: https://en.bitcoin.it/wiki/How_to_import_private_keys_in_Bitcoin_Core_0.7%2B
Worked, exept that i dont see my Bitcoins, I just see the address in my wallet.
What else can i do to get on my bitcoins?
There are 2 possibilities (as has already been pointed out to you).
The first (and most likely in my opinion) possibility is that you perhaps extracted a private key for the wrong address. How do you know that this address should have bitcoins associated with it? Are you aware that when you send a transaction, the wallet creates a new address that it keeps hidden from you and moves the bitcoins (as transaction change) to the new address? If you still have access to the old wallet and the bitcoins still show up under the old wallet, then you should run listunspent to get a list of all the unspent outputs in the wallet and the addresses that each of them are actually associated with.
The next possibility is that you imported the correct private keys, but you did so without re-scanning the blockchain. If this has occurred, then you can rescan the blockchain and the bitcoins will show up.
It would be helpful if you could share the address with us that you are trying to import. We could then investigate and make sure that it is the correct address and let you know a bit more about what you've done.
It is generally dangerous to be manipulating private keys if you don't understand what you are doing.
