Unconfirmed transactions on QT wallet

Hi, I have an old QT wallet. Earlier this year I sent 4 LTC to the now defunct BTCe. However, the transaction never got verified and my wallet currently has a balance of zero.
The Transaction ID is: 8180f26bd8d42bb8c0a78756fab5e9c5a450ac2b46af18e9bfca4817224c91d7 and my wallet address is: LY1TQFBf2ntuwVKwB4jTBVobZUpruaJapP.

I have tried to rescan to no avail. I am now installing the QT wallet on a different machine and going to try and use the command sendrawtransaction with the hex code. I have got to wait for 5 years of blockchain to download so it may be sometime.

Is there not a way I can reverse this transaction? Or is there another way I can sort this problem out?

I have the.dat file for the wallet but not sure how to use it.

I look forward to your responses. Thank you.

If the transaction was never confirm in the blockchain,

you need to install the latest version of the wallet and abandom the transaction.

Cheers
