Reddcoin wallet collision error

I have been involved in passwords for over three years and I am not a rookie. When I first built it a few years ago, I mined a lot of Reddcoin and the project was really good. But I did not have much trouble in my wallet in my life! I am using Windows 10. I downloaded and installed the latest Wallet 2.0.0.0, deleted everything except the wallet.dat in the appdata \ roaming \ Reddcoin directory, saved it in the appdata \ roaming \ Reddcoin directory, and launched Wallet. I started loading from the disk and after 2 days, I have not enough wallet. The original wallet.dat wallet.dat and the newly received wallet.dat are thought to be combined in the redo process.

Two wallet data is combined and it is displayed as an error, and the wallet itself is not opened. It has been managed, tried, and saved for 2 years, and it is not used and it is hard to use.# Insert Code Here
