Contracts on Ethereum are autonomous. (Yes, a machine can now own money.) Owning the private keys to the address that created a contract is meaningless unless the contract has a rule that allows the creator to withdrawal the money. (And unlike accounts, contracts do not have a corresponding private key to the address of the contract.)
Can you please explain how you created the contracts? Were these standard contract wallets? If so, the money can likely be retrieved if you are the original owner. If not, there's not really much that can be done without more detail about the contract you created. (The source code of the contract will be needed.)
edit: I looked at your contract's code. It looks like it was the standard Ethereum contract wallet. If you have the private keys for the address that created it (0x4a5cfa400c63347c7c98d03c059b661d4f2edf20), you should be able to withdraw the funds from the contract. (Assuming you didn't put any rules on how the funds can be withdrawn.)
For those that are interested on how I figured out this was the standard Ethereum Wallet contract:
It looks like you're already able to access the money from this contract wallet account. I see on the last line:
Invocation Result: Balance change from 1,265.9750153799 Ether to
edit2: I think I'm understand the purpose of this question now. (It was hard to understand what you were asking at first.) It sounds like you reinstalled something and are trying to get your wallet contracts back on the screen.
You'll need to re-add the contract wallet to your client.
- Click the Wallet Tab at the top
- Click Add Wallet Contract
- Click Import Wallet
- Paste this in the Wallet address: 0xdf2bf1aac908a97becb9a1fd43d3cbfda12379dc
- Click Create
You should now see your old wallet contract and have access to the funds again.
