i did not knoe it was possible to do this one please explain more details for us
It's possible with forked coins. You can send Bitcoin Cash to a Bitcoin address too and since LTC was forked from Bitcoin it's possible to do the same.
Try this OP, people have managed to recover their money by following these points. It was posted in a few places including reddit and litecointalk.
You're going to need a fully synced Litecoin-qt install for this to work, which may take 5-10 hours.
1. Open up this page, BitAddress.org, and LiteAddress.org
2. Copy your private key into the Wallet Details tab on BitAddress.org. Scroll to the bottom and copy the "Private Key Hexadecimal Format (64 characters [0-9A-F]):" value.
3. Go to the LiteAddress.org page and move around your mouse until the Wallet Details tabs appears. Put in the hex key from the previous step in here.
4. Select and copy the compressed WIF key (NOT the one starting with 6). Also keep note of the "Litecoin Address Compressed" from the first half of the page (starting with L)
5. Open up Litecoin-qt, then head into the debug console.
6. Run importprivkey "" (with quotes).
7. Once the import finished, run addwitnessaddress "".
8. Wait for this import to finish as well. Take the M-address from the console and use this tool to convert it to a 3-Address.
9. If the funds haven't shown up yet, close Litecoin-qt.
10. Restart Litecoin-qt along with a rescan. This varies by OS, and in most cases will happen automatically if you wait for 10 minutes or so before restarting.
