Wallet.dat is damage

I have big problem.
I have wallet.dat file damage.
I can’t move my coins and the wallet is closing after while.
This is about my buckup file so I don’t know what to do?
Could you help me ?

Back up wallet, then try:

C:\Program Files\Reddcoin\reddcoin-qt.exe -salvagewallet C:\Users\USERNAME\AppData\Roaming\Reddcoin\wallet.dat

Did the above solution work for you?
