Dev one question i have new wallet and old wallet.dat where are my coins, how can i get them in new wallet.
You have two options: First step
backup the new wallet.dat file and the old one.
Scheme A:
Copy-Address of one available SIL address out of the "Receive Coins" tab out of the new wallet.
After this step within the 611 data directory you may then delete all files
- Linux/Unix: ~/.611
- Windows: %USERPROFILE%\AppData\Roaming\611
- Mac OS X: ~/Library/Application\ Support/611
Copy the old wallet.dat file into the 611 data directory and restart 611-qt beta2.
After 611-qt has loaded all blocks of the blockchain you should have your old SIL balance available.
Just press "Send Coins", paste the SIL address of your new wallet and transfer your available balance (minus the transaction fee) to your new wallet.
After this step wait a few minutes and then delete all files within the 611 data directory again. Copy the new wallet.dat into the 611 data directory and restart 611-qt beta2. After 611-qt has reloaded all blocks of the blockchain you should have the transfered amount available in your new wallet.

Scheme B: If you do not like to pay the transaction fee you can use the debug console to export the private key out of your old wallet.dat and reimport it into your new wallet. Reloading the blockchain should make your balance available in the new wallet, too.

Just follow these steps:
